Graphite Design Tour AD SLII Driver Shaft
Graphite Design added a light weight shaft to the popular Tour AD Line in 2014. This shaft, like many others in the light weight category, ranges from 50g to 60g, with stiffness corresponding to weight. In this weight range, we see higher torques, but not so high that I would be concerned about head stability. These shafts are designed for swing speeds in the 60 to 85 mile per hour range. The 60g SR flex extends to the 90 mph range. My swing speed in in the high 90′s with the occasional 102 showing up and I am playing an ultra premium 59g shaft. Light weight driver shafts, made out of high quality carbon fiber are the future of golf for many of us. That couple of grams I lost in my latest shaft change has given me a new range of control and feeling without any increase in dispersion. In fact, I am hitting more fairways than I ever have now that I changed to a sub 60g shaft.
Radial integrity of the Graphite Design Tour AD SLII is exceptional, the review samples averaged 98.5% with a 0.4% standard deviation. The hoop strength is high for this weight range, and distinctly different in the 4 vs 5 models. This measurement is new for my knowledge base.
This is a unique design, there is no close match in the database. The tip to butt ratio and the tip load and butt load deflection analysis shows it to be a high launch high spin design consistent with what Graphite Design is saying about the shaft. In the speed range it is designed for, that is what will optimize distance. Tip torque is tight. Butt torque is in the range that transmits adequate feel in light weight shafts. If your swing speed is below 90 mph and you are looking for a quality shaft this is one you should be testing.
