The Graphite Design Tour AD DJ was the second shaft released in the current Tour AD series. It followed the original Tour AD-DI and was designed to promote a lower launch by stiffening the tip.

The Graphite Design YS-Hybrid was a shaft I discovered through customer trials. Almost every time I sent a fitting client out with a few hybrids to compare, they came back and asked for the YS-Hybrid shaft. Torque of the S flex was 2.5, about average for hybrid shafts. The design resembles the Nippon Modus3 iron shaft. A quick loss of stiffness in the mid section, with a long stiff tip. The closest hybird shaft I have seen since is the UST ATTAS.

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.

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.
