Hey Team Titleist, I have been looking for a new set of irons for the last couple months and I think I have decided on the AP2's but I can't figure out which shaft I need. I am 15 years old and about 5'5 tall and I hit my current 7 iron about 150-155 yards. the 2 shafts that my golf pro told me was the True Temper Dynalite gold XP R300 or S300. Do you think I should go with the regular R300 or go with the stiff S300.I have always played regular flex shafts but I have heard that you have more control with a stiffer shaft. any help would be appreciated.
