Along this line, the current trend with composites among the tour players is definately toward more flexible (and somewhat lower bend point) shafts that are very low torque. I want to say that Gary Adams was the first to explore this in a retail club with the shafts in the original McHenry Metals drivers, but they may have been others before him.....
Basically, it appears that the flexpoint and frequency are much more related to the feel of the shaft, and the torque may somewhat effect feel but much more manifests itself in the dispersion of the finished club.
