the group of guys i play with has a core group that collect and play hickory clubs pretty frequently. we go on extended golf trips 4 times a year (i.e. 6 rounds in three days type of trip) and the core group will always play their hickories for at least one round during the trip, usually during the afternoon re-routes that don't count towards the team game. there are several of these guys that should seriously consider playing nothing but hickories, or reconsider the stiffness of the shafts in the clubs they usually play.
hickory shafts really make you slow down and smooth out your swing because of their flex, often for the better.
typically the guys play noodles. wilson 50s, 'ladies' balls or something similarly soft.
one of the guys currently plays to a 7.5 and i've seen him break 80 numerous times playing with hickory clubs on a >6000 yard course even though he has a serious case of putting yips. probably has something to do with him looking like old tom morris and being in his late 60s with a buttery smooth swing:
