Re: Titleist vs. Mizuno ironsI've hit the AP2s and the MP-57s and I would honestly lean toward the AP2s. They don't have that butter feeling that the MP-57s get so right, but they instead have that compression *click* that the old Cleveland TA-7s could produce, and that's a whole different way to feel sweet, sweet contact. They're also noticeably longer.
I honestly don't think one is better than another. Still, if you want the smoothest contact around, I do think the Mizuno forged blades are absolutely perfect for that. I know the AP2s would be longer for me by 2-3 yards a club, but I also know that I trust my trajectory with the 67s more than I ever have with anything else, and I know that I can "work" my shots with these clubs. I think they're perfect, but that's not to say that Titleist can't make a perfect club too - I've never hit the new Titleist ZM or ZB blades, which I'm sure are so, so pure.
Can't go wrong.
As an aside, to whoever said the J36s were sweet: I actually agree there too but they, in my hands, didn't transmit the compression feeling as noticeably.
