I am a Titleist Brand user and would like to get my 12 & 14 year old boys to start with 712/714 AP1 Irons and I would like your recommendation on which shaft is best for them as they enter their teenage years. My oldest son played on his middle school golf team. My thought is the True Temper XP 95 - R300 ? The 712 AP1 set he has now has the Dynalite Gold XP R300 (they might be to heavy of a shaft for him now). Should I consider the XP 95 - R300 ?
