i play with predators on all my players.... consistency i guess... kinda got into them through all the poolhall dudes where i play... my SW shafts are all different. New SW has shafts at 3.6, my old SW has a shaft at 4.0 and actually is single handedly the best shaft i've ever played and i had Drexler put a yellow micarta on it with a moori med... just awesome..
now for the dumb question-smart shaft? and what's an adaptor for a shaft-you mean you can use it with any joint? that's gotta effect playability...
thanks
