October 12th: Update added below.
Hot news from Quadra Composite Techno! They are releasing all new white Fire Express Prototype shafts that produced a strong penetrating trajectory for the fast swinger and quick tempo. This shaft is made for stability and to take the left side (hook/pulls) out of play. The torque is lower than the standard Fire Express but the shaft still gives great feedback and feel thanks to the 80t high grade carbon.
The original Fire Express is still one of the best performing low spin shafts in Japan and easily one of our best sellers. This new Prototype will appeal to the even faster and harder hitter. Like the original FE, they will be available in 65 and 75 models.
Also being released are white Fire Express Prototype iron shafts! I’ve asked Quadra to confirm the materials of the shaft but I’m guessing 50t carbon which like Crazy would make them the highest grade graphite iron shafts in the golf world today. The iron shafts will be available in 118g stiff flex and 120g x flex shafts. Steel like accuracy but graphite like feel and kick with consistent and predictable timing and impact. Check out the shafts in the pro shop here!
Update: I spoke to Quadra Composite Techno yesterday to ask them what kind of differences were there with the prototype and the standard model besides the torque numbers and rigidity distribution. Technology wise, the new prototypes feature an additional wrap of 70t carbon on top of the full length 80t carbon to reinforce the butt area. This stiffens up the butt over the standard model and provides a lot more stability especially for those with aggressive transitions and lots of wrist lag. The Prototype is made to provide similar big distance as the standard shaft but with more control for the hard hitter.
