I got a TSR3 driver and love it, but the only thing that isn't perfect is the grip size of my HZRDUS Red CB stiff shaft. The butt diameter of the shaft is .615, slightly larger which with the standard grip that Titleist put on it means it feels just a bit bigger than standard which I don't really like. What is the remedy to get it to a standard diameter? Should I regrip with a standard grip and stretch it at least a 1/2 inch? Should I regrip with a different core size grip to get it to the standard .900?
