GRAPHITE DESIGN SERIES G
The Graphite Design G Series of shafts was introduced in 2011. A large bundle of them arrived recently for review. The measurements got my attention. I would put this shaft into the same design group that I see with the Mitsubishi Diamana Blue, the Miyazaki JDL and the Matrix Ozik Xcon. A soft mid in relation to the tip and butt. This fit is generally suitable for the golfer with a quick, aggressive transition. We can see this by looking at the average EI and GJ profiles of the Graphite Design G Series.The key to the radial quality and respectable torque numbers of this shaft may be due to the attention paid to fiber orientation in this shaft. I lifted this illustration from the Graphite Design website.
There are 6 different fiber orientations used in this shaft. The bias plies are at different angles and sandwiched in between the tip to butt, linear fiber plies. Not all plies extend the full length of the shaft, But from a measurement perspective, the layup works. With radial quality numbers like these, this shaft, even in the light weight models, is suitable for the rotating hosels in todays current generation of driver and fairway designs. Looks like were are going to have to take some of these to the range and see what they feel like, stay tuned.
