Modart T55 PROTO Wedges!

Modart PROTO

Introducing the MODART T55 PROTO!    This wedge features the same shape as the original T55 (found here) yet the sole is wider and the milling effect altered for a new look.  Modart also applied a black oxide finish so the player can feel the steel differently than the original and plated model.  If you look closely what looks brushed is actually milled then slightly polished by hand.   Follow the Jump we have many photos…

MB Seven CB

Introducing the SEVEN Blue2 Prototype,  this is a true and real prototype set un hit and brand new only 2 sets were made and just 1 will be sold.  Made of S15C Forged hand ground 100% Japan made.

The concept was a collaboration with one of TSG’s popular forum members Chiromikey a very skilled golfer I was having a conversation with one day and offered to work on something fun together his suggestion was a blade with strong lofts with a gap wedge using the same head mold as the irons 4-AW instead of 3-PW as most blades are sold.  Designed with a slit cavity that was CNC milled below the muscle made with extremely thin top lines and very little offset.

Prototype is a word thrown around too easily in the golf industry,  companies are labelling products prototypes that are nothing of the sort.  From Wiki : A prototype is an early sample, model, or release of a product built to test a concept or process or to act as a thing to be replicated or learned from.  Many hate to admit it but the word has at the very least peaked their interest on multiple occasions but how many of us actually have the chance to play “real” prototypes I’m talking only a few made as a brand is evolving a concept into a retail release?  My guess is not many.

Here is your chance,  this is a one of a kind set of S15C Forged hand ground 100% Japan made (of course) Seven Blades 4-AW  brand new a one of one concept.  It’s special,  it’s rare and its a “real prototype” click read more to continue…

SEVEN Hizukuri PROTO – L

SEVEN Hizukuri Proto L Putter

Some Japanese Golf Clubs are still made the old fashion way like SEVEN’s Hizukuri Putter –  It starts with our heavy head made of S20C the furnace is heated to about 1200 degree’s putting the S20C on the verge of melting which makes it easier to manipulate and bend by hand.

The crafter then pulls the head from the fire while it’s glowing red and pounds and pounds with a hammer over and over again layering the steel and compressing it while pulling and bending the neck section to shape.  If you like what you see more after the Jump…

SEVEN PROTOTYPE – V1.5 SS400 Cavity Blade


SEVEN – Every time the brand “Seven” produces a new model many True Protos and test samples must be made,  we experiment with different grinds, finishes, specs, and anything else we think is needed.  Today we pay homage to one of our most special sets of True-Protos and while may look similar to the first version of the cavity blade I would consider it’s DNA version 1.5.

The original CB as seen “here” features blade like specifications to face progression (offset) to top line thickness which is in the 4mm range.  This prototype was designed to bring it a little more forgiveness while finding out how these changes effect feel during impact.  Follow the jump to learn what happened with this one of a kind Seven True-Proto’s.

Fourteen Type-7 Driving Iron

Fourteen Golf Type-7 Driving Iron Hybrid

Fourteen Type 7 Driving Hybrid Iron – You seen it on the PGA Tour at the Shriners Hospitals for Children Open in Las Vegas,  we have been seeing variants of these for more than a year on the Japan Tour and now it’s been sent to us for testing and eval.  I’m going to keep this short and sweet,  This is a near perfect driving iron that is highly refined,  from it’s angles, feel, forgiveness and overall performance it hit’s all marks for the player type it’s intended for.

So who is it intended for?  I’d have to say the low/mid handicapper who want’s to shoot tight accurate bullets to land in 2 on a par 5, or I can imagine it’s extremely usefull off the tee on tricky par 4’s or longer par 3’s,  yes there are higher launching more forgiving driving irons and hybrids that can be used but none as evolved as this in my opinion.  Follow the Jump for more pics and review…

Ryoma Special Tune w/ CRAZY MOFO Prototype Impressions

It’s my 4th Ryoma driver now,  I’m all about these and have been for quite some time.  The D-1 V-Spec has changed my driving game and even my wife plays one.  It’s less stressful on the brain when a mishits fly a lot straighter and longer.  My addiction started with the V-Spec 9.5 degree head.  It was better than anything else I played up until that point but trajectory still was a little low for me,  enter the 10.5 V-Spec which has been in the bag almost forever in club Ho’ing years.

Then more recently it became a 9.5 Special Tune which although higher than 9.5 conforming model it still flew a little low for my bones so…. Here comes my new babe,  The D-1 V-Spec Special Tune but this time in 10.5.  Glory!  It works perfectly and I’m getting 10 yards on average more distance and occasionally 25!  Don’t believe?  Ya Neither do I.  My score has gone up as some holes I have to hit a 3 wood now but I’ll work that out too U guess.

Geotech Prototype RF700 Forged Review

Geotech is Japan’s leading components maker and has long provided high quality component designs at reasonable prices. They’ve worked hard to provide a mix of tweaked and original designs for players of all budgets looking for great feel and performance. Their Prototype RF700 lineup has been very successful with its drivers, woods and utility providing top notch performance at a fraction of the cost of big mainstream brands. This season they decided to release an all new Prototype RF700 Forged iron, an original design made for wide range of golfers.

Geotech notes that the Prototype RF700 Forged is a CNC machined muscle back iron, forged from S25C steel.  Even though its a muscle back, Geotech has put its target audience as players ranging from a 0 to 25 handicap which is pretty wide range of skill levels. After examining the iron’s design and giving it a try I can see why. The RF700 sets up very much like a blade but the back face is almost cavity like, much like the Romaro Ray H I recently tested.  Because of this I’ve decided to call the RF700 a neo muscle cavity, a hybrid of sorts that has the feel and playability of a blade but the forgiving characteristics of a cavity back.

The unique design of the RF700 features a forged head which is then CNC machined into the finished head you see here. This intricate machine process creates what Geotech calls VFTD: Vetical Flow Thickness Design. From top to bottom the thickness of the iron varies from 4.7mm at its thinnest to 12.9mm at its thickest.  What this does is create a balanced head that provides feel, launch and distance. The thinnest area of the iron crosses  right through the center to create maximum rebound off the face and more distance, while the thickest area is the lower cavity portion which increases MOI by lowering the CG for easy launch and a wider sweet area.

Even though the thickest part of the iron is towards the sole, the actual sole itself is long and narrow. The front edge is slightly killed for some leading edge relief and the sole itself is rounded to provide some stability and control though different lies including firmer turf. While many irons today – especially JDM models are showing more bounce, the RF700 keeps bounce at a minimum with the 9i feauring 2.5* and the PW 3.5* of bounce.

The face profile of the RF700 Forged features a bit of everything as it has a reasonably straight top line paired with a boxy and higher toe as preferred by better players. But at the same time, its longer from heel to toe stretching the sweet spot side to side. The leading edge is also ever so slightly rounded, again for added ease of use and to promote more pure impact in various lies.

At address, better players will appreciate the thin top line and the lack of offset. It certainly does look like a muscle back at address as there is no sign of a cavity. When I first got the iron, I did notice how it set up at address like a blade (is it a blade or not?) but the longer face really stood out for me.  For the average golfer there are many features of this neo muscle cavity like its lower CG and thinner center as well as its rounded sole and leading edge.  The longer face allows for players to miss towards the toe or heel to minimize lost distance. As an average golfer, this was a playable iron for me even though its supposed to be a muscle back like design. Feel is very good  and the ball launches well and jumps off the face at impact very much like many cavity backs today that do feature thinner faces.  It may not be as pure as other blades that feature thick muscle areas right behind the sweet spot but the RF700 undoubtedly feels forged. I handed the iron to a scratch golfer practicing on the course and he right away said “oh blade” and he stuck a few and said “very nice”.

The Prototype RF700 Forged is a cavity back in disguise as a CNC muscle back design iron. It has balanced performance, with good feel, easy launch, and good distance and forgiveness. Many people will like its clean but interesting looks, and even more will like its price tag and the fact it can be bought as heads only or built by Geotech with any shaft or grip to the customer’s specs.  It offers something for every one in a good quality package and good price. The RF700 Forged is already in the pro shop and there are even matching wedges!

Geotech Prototype RF700 Hi Cor Alpha Spec Driver!

Geotech sent me their new Prototype RF700 driver to check out. The great thing about this driver is its their Alpha Spec model which is Hi Cor/Non conforming at close to 0.88 COR. Non Conforming models seem to be making a come back of sorts these days after nearly reaching extinction with most major manufacturers moving to USGA conforming heads in the last decade. Recently however, many amateurs who play for fun and recreationally simply want more distance and don’t mind playing a non conforming driver.

The RF700 is finished in all black and it looks pretty good. It is aimed at the better player all the way up to average golfer wanting a head that maintains a traditional shape and has a square face angle.  With a non conforming SP700 face, this driver is obviously aimed at distance performance but at the same time Geotech did not want to sacrifice control and stability.

The SP700 face features variable thickness which provides pure feel when struck in the center. The CG point is located right in the center of the face and pushed back deeper in the head for a high launch but low spin trajectory. The face of the RF700 is actually on the deeper side which allows for control and workability.  It’s score lines do not go all the way across the face which seems to be preferred by those looking for less spin and distance.

The head itself is 435cc and features a semi high back design. This allows the player to produce a level blow on the ball but still create a higher launch with low spin. The hosel insertion depth has be increased on the RF700 to create more stability and control.

Players will like the look of the RF700 at address as its shape is on the compact side and face angle open to square. The 9.5* is spec’ed as 0.5* open and the 10.5* as a 0* square face. The 10.5* tester I had certainly appeared square at address and looked to have very little bulge.

I spent a bit of time with the driver at the range here and it was more forgiving than I expected for a 435cc driver with deep face. Shots of the toe and heel did not lose too much distance and those struck in the middle launched very easily and with both good carry and run. As with most Geotech drivers, the sound is more muted. They never seem to make drivers that produce that high pitched metallic impact sound you can find in many drivers today.  Like usual, the strength of Geotech’s heads lie in its cost performance value. The RF700 is no exception as it provides pretty good looks, feel and performance for a fraction of what other top JDM Hi Cor heads cost.  I’ll be adding it to the shop for those who want to try it out this week.

Geotech Prototype RF700 Fairway Wood and Utility Review

Geotech Golf has always been known to make some very nice metal woods with very good cost performance attractiveness. Geotech’s roots afterall were in the metal wood manufacturing business beginning over 23 years ago as part of Dynamic Golf. In the past I’ve tried many Geotech fairway woods and utilities and come away fairly impressed with overall performance especially when factoring in costs. Geotech has become Japan’s top components brand and that is a lot to say in probably what is the most demanding and picky golf market in the world. What other country has every global golf club model PLUS all its own Japan only models from all the big golf brands. Japan’s consumers demand premium selection, so the brands oblige.

Simple Gets it Done…

Geotech, being a smaller company, has always thrived on creating a wide selection of performing golf clubs, many of which are no frill clubs that simply do their job. When I saw the new Prototype RF700 fairway woods and utilities back in February at the Japan Golf Fair, they immediate caught my eye because of their simplicity. Believe it or not there are still golfers today who prefer simple and back to basics and that is what the RF700 line provides.  Geotech sent over a couple of demos for me to try out this week, a Prototype RF700 18* 5 wood and also a Prototype RF700 18* 3Utility.

Handsome looking faces…

When comparing the two clubs, aesthetically they share the same visual design which makes sense since they are from the same line.  They have a very similar face profile and shape with the RF700 fairway wood being slightly deeper allowing for versatility off the tee or deck and allowing for a slightly higher CG point.  The fairway wood is designed to spin less giving more distance and a stable penetrating trajectory. It has a smaller gravity angle and its square to open face is meant for workability including draw and fade. The RF700 Utility is shallower and has a lower CG allowing for an easy launch from a variety of conditions including bad lies.  Its higher launch and higher spin allow you to attack the green using the utility instead of a long iron from a distance and get the trajectory and back spin you need to stick it close to the pin.

Pleasing at address…

The Prototype RF700 is aimed at the low to mid handicapper and better player. Those players will appreciate the smaller more compact head sizes and the simple clean lines at address. The RF700 fairway wood features a strong 3 wood with 13* loft. The 13* is the only RF700 with a closed face at 0.5*. As the lofts increase the RF700 fairway woods have increasingly open faces, in other words the 15* is 0* square, the 18* 5 wood is 0.5* open, the 21* 7 wood is 1.5* open. This allows for more control and avoiding a pull or hook with shorter woods which can be common among faster or harder swingers. For me the RF700 Utility looks very much like the very popular Royal Collection TRC Utility at address.

Focus on stability and control…

Geotech wanted to ensure stable and firm flexes with the Prototype RF700 line so instead of a standard 30mm insertion depth, the hosels of both the fairway wood and utility have hosel depths of 40mm. This stiffens up the tip of any installed shaft to create more stability and control again aimed at the better player.  The Prototype RF700’s also provide rather solid feel at impact. The body and face are all made of SUS630 stainless steel creating a more subtle thwock at impact rather than the high pitched tink we hear from many metal woods today.

Attractive Cost Performance…

The sole design of the RF700 features a dual level sole with cut away trailing areas to minimize friction at impact with the turf. This is about as technical as the RF700 gets but honestly, it doesn’t need to be any more fancy. I like its clean looks and it feels solid at impact. Its design creates a workable and stable ball flight and I find the the shape of the fairway and utility heads blend well together ie if you carried a RF700 3 and 5 wood and then 4 and 5 Utility it would seamlessly flow from club to club.  Certainly the RF700 will not rival the PRGR Egg Spoon in a distance competition, nor will it outdo Royal Collection when it comes to feel, however at its price, it is a solid performer which will appeal to many golfers who don’t have the deep pockets for the big name brands but want to build their own clubs to their own specs (the FW takes 0.335″ tip shafts while the UT takes 0.370″ tip). So what will the RF700 set you back? It’s 80.00 a head for the fairway wood and 70.00 a head for the utility.  Even with the ultra strong Japanese yen, those are pretty darn good prices. Look for them in the pro shop this coming week!
