Hi Bryan,  We posed your question to our Shaft Guru, Don, and here's what he had to say. 

The idea of shaft torque affecting dispersion makes sense on the surface, but torque is only one variable in the mix.  Since the hands are rotating into impact, shaft bend profile (sum of butt, mid and tip flex) and weight will also affect where the head is at that critical point.  If all shaft values are optimized for a particular players swing, the head will be square at impact and travelling at maximum velocity for the player's swing speed.  This will result in the longest, straightest drives and is probably the reason he hits the 910 D2 with the Kai'li 65 so well. 

Reducing torque from a player's optimum value may actually leave the head open or closed depending on his swing and reduce distance if the player has to compensate to keep the head square.  So thinking of torque as a tool to reduce dispersion is a defensive way to look at the shaft.  You may reduce dispersion slightly on a bad swing, but will give up distance and maybe overall accuracy as well if it induces the head to be open or closed.  Another thing to keep in mind is that there is no industry standard method for measuring torque.  Comparing torque numbers from different companies is really not possible or advisable.  The idea of optimum torque for a given swing speed is one of the principle features of Titleist shafts and combining it with the bend profile and proper weight produces shafts that are well matched for flexes as well as speed.

As always, we recommend working with your certified fitter and letting actual performance be your guide to shaft and club selection.
