Cant you then just go old school and just hit heavy, med wt and light shafts on the range (guess demo days are not that old school)..i used to just ask to try a buddy's club or even a total stranger's...they would like that because it gave them the nerve to say try my driver..i swapped a driver that way....question....would adding lead tape to my graphite irons just be counter productive? I could just play the steel set, but my graphite irons do have longer shafts and stronger lofts..graphite is also nice in cold weather.
