I'm getting back in the game and do not have a budget for new clubs. I'm using my son's generic set cavity-back with graphite shafts. Bought at Sports Authority. 6 - PW irons, 4 & 5 hybrids and 3 & 5 fairway woods. I'm sure it's handicapping me some, but I have no choice. I was thinking of taking this set to a club fitter to get fitted for loft/lie and new grips. Think it would help? Thank you!
