I asked a similar question a few weeks back with no real response from Titleist so am trying again.
I am going to switch out my AP2-716 6i and 5i to AP3-718s. (Maybe even an AP3 7i too.) I was fit for my AP2s with XP90s, though I am not necessarily convinced they were the right shafts for me. Be that as it may, I am now comfortable with the XP90s and have no desire to change them out at this point. So my question is, should I just have XP90s put in my new AP3 5 and 6 irons to match the rest of my irons, or would it make sense to use something else like the AMT with the stock, ascending mass shafts? Would those shafts be similar in weight and feel to my XP90s?
