Can anyone give me the performance difference of these two shafts in a Cleveland Classic 290 driver head, ball flight, spin rate, swing weight? The NVS shaft is 65g and the Miyazaki is the C Kua 59 from a Mashie 3-wood which I would have lengthen to play at 45", in fact both shafts would play at 45" in this driver. I am interested as to how the swing weight would change since the stock shaft is the C Kua 39 or 43, I think.
