Not from a scientific point, but from a club sellling aspect: I have had sucess in fitting flex (cpm) for max distance (with accuracy in mind) and using torque to tweak to a customer's sensation.
IE: Every had the client who REALLY needed a softer shaft to have a better club, and when they demoed, though they hit it better, just whined and whined about how "whippy" the shaft was. Solution: get a shaft that plays to the same flex but a stronger torque. This equals SALE. The reverse is true. Is it absolutely the best shaft for them, most likely not, but then again only the truly open minded clients buy those. Others buy from someone else who most likely has less skill than you, isn't as concerned with the client's club performance, and plainly sold them what they asked for.

OK, let's assume that my calculations were in the right order of magnitude, and examine your generalizations: >1. Stronger swingers and maybe faster tempos need lower torques? That has been a principle accepted by many "authorities" in fitting. It does agree with my calculations. >2. Bigger (wider) heads need lower torque? Absolutely! Bigger heads put more than proportionally higher twist on the shaft. >3.

You are assuming that a softer shaft means more distance. I don't believe this in general. But I suspect this would be a worthwhile strategy for fitting some golfers. In the meantime... Charlie B just said he was going to try just the opposite. He has a strong player (Canadian Tour) that hits an X-flex best but says it feels boardy. He is going to try an X-flex with a higher torque rating, to see if that gives him the distance with a softer feel. It will be an interesting experiment. If I had to guess, I suppose that Pat's comment about dispersion will spoil things a little. But you never really know until you try it. Cheers! DaveT --- Incoming mail is certified Virus Free.
