I'm going through the same thing right now. I've had the AP2s for almost 2 years now, and I've noticed my distances have been about 5-10 less than what I upgraded from. I just rolled with them until I got frustrated enough to see if I needed something else. Sure enough, they're too heavy and a tad too stiff for me. The Mizuno shaft optimizer fitted me for the Project X 5.0 (Flighted 5.5) or the Dynalite Gold XP S300. I'm looking at going to AP1s or trying out the new Callaway X Hot Pros. I have a 6 iron demo of the X Hot Pro and it goes a mile, but that's probably because it's 27 degrees.
If you don't mind me asking, how much did you get for your AP2s on Ebay?
Thanks for the reply! Yea, I thought that it was just me and that I should give it a while with the S300s, but my iron play has been horrible... it felt like I was swinging rebar. The Nippon 105T shafts (which are what I am getting again in the AP1) are a little soft, but not too soft. If you don't swing to "jerky" the ball will go a mile.
I sold my AP2's on eBay for $420 (incl. shipping) and they sold within 10 minutes of listing. Titleist clubs have extremely high resale value, especially if they are in good shape.
This was my listing: LINK
