If there is enough epoxy in the bore it will not allow the shaft to twist during the swing, like if you have a shaft that has a 2.5* torque but you fill up the shaft with epoxy to just less than the hosel bore you in essences are turning that shaft into a .5* of torque instead of the 2.5* shaft that the other major components were made for . . .
Mr. Kennedy, are you suggesting that almost all of the 2.5* of rotation of the tip relative to the butt that occurs when a standard 1-ft-lb torque is applied to the tip of a 2.5* torque rating shaft occurs in the last inch and a quarter of the tip of a 46-inch shaft? Interesting. And very enlightening. I thought that since the last 30-mm of tip is securely bonded into a VERY torsionally stiff hosel that it probably doesn't twist at all and all of the twisting of the shaft during the swing and impact of a golf club occurred in the 40-some-odd inches of the shaft above the hosel.
