I currently play the 714 AP2 irons and really enjoy hitting them! I was skeptical at first, mainly because of the shaft. Wasn’t entirely sold on it being right for me but the club heads themselves are great. IMO one of the best looking and feeling AP2’s Titleist has created! Until the new 718’s! Wow! Great looking club! I had a chance to hit them and was really impressed. The rep told me that it’s all in the shaft and that’s what makes the club perform. Project X. My question is, do I need to upgrade all together or keep the same heads and just reshaft? Thoughts?
