Seems like quite the difference of opinion but it is starting to make a little sense (I think). Dave, I have been out of engineering school for quite some time but your math looks right to me. From that and some of these posts we can generalize a bit. 1. Stronger swingers and maybe faster tempos need lower torques? 2. Bigger (wider) heads need lower torque? 3. The next thing then is could we maybe move a customer into a softer flex with lower torque to improve distance without a loss of accuracy or is that too much of a streach? My first post after 2 years caused quite a discussion, nice Mike
