He had a Harrison 1.8 in 1 of his drivers and it lasted longer then the Harrison 2.5's that he prefers. It very well could be torsional stress that is causing all the breaking.

I guess I'm having trouble understanding this, though it may be OK. My questions: (1) What do you mean by "enough torque"? It sounds like you mean a shaft with a "torque" rating higher than some number (like 3.5 degrees), but I'm not sure. (2) If that's what you mean by "enough torque", why should that have anything to do with breaking shafts? My own reasoning would be: - Maybe the shafts are breaking from torsion stress and maybe not. Bending stress? Shearing stress? I suspect both are at least as likely as torsional stress. - Even if it is torsional stress, I'd expect that torsional STRENGTH, not torsional FLEXIBILITY, would be the key. Why would you expect torsional flexibility to prevent breakage?
