Since the TS hybrids and U510 both take .370 hybrid shafts, what is the tip trim recommended for the U510 4 iron? I have an atmos blue shaft with a TS hybrid tip and want to put that in my U510 but am not sure of two questions? How much is 19* hybrid tip trimmed when installed in the adaptor, and how much tip trim wound you want for a U510 4 iron? Thanks!
