Hi, i recently started looking for a set of irons to buy. i have used png my entire 30 years. now i have begun to hit your AP1 714 irons at the store and really like the feel, look and distance. i am an average player, about 15 handicap and not a fast swing so i have used regular flex shafts. when at the store i noticed there was two different XP shafts in regular flex. that be the 100 and 300. i am not sure which one i like better or which is better suited for me. what i would like to do is try each set on the course before i buy. Is this possable and how do i go about doing it. i am located just south of Boston, Ma. Thanx Larry
