i haven't tried using lead tape before but i'm a pretty competitive player and want to give it a shot. as far as putting it in different locations, can anyone give me insight to what it should do/effect? do most pros place lead tape at 12, 3 and 9? if say you put it at 3 and 9 o'clock? or 12 o'clock? in the throat and under the grip, etc? how do you measure swing weight? thanks!
