The sixth version of the Graphite Design Tour AD driver shaft line releases shortly. We got an early look at the 10 shafts in the MJ series. They range from 53 grams to 87 grams uncut. The profile is consistent through out the weigh range, each weight/stiffness increment has exactly the same bend profile. They simply get heavier, stiffer and have lower torque.
Since the original Tour AD DI, the Graphite Design AD DI series has had a mid shaft stiffness ‘bump’. Each model has varied the degree and position of this mid shaft stiffness design.
KBS C-Taper Lite Parallel
Parallel shafts have been a favorite of club builders with frequency machines for much of the time I have been engaged in club building. My involvement with a group called the PCS introduced me to the concept of frequency matched shaft sets. Before I developed an understanding of EI measurement, I was and avid practitioner of frequency matching. As I developed an understanding of the golf shaft through EI, I switched to using constant weight taper shafts exclusively. It is only recently, in the preparation of this review and another parallel shaft that I developed a new appreciation for the genre.
