Guys, I wanted to pass along a recent observation that is new to me. May not be to you.
I bought new fitted Mizuno 800 Pro irons this year. Had to drop back to regular shaft from stiff due to age/swing speed. Been playing graphite for years because I like to feel the head of the club in the swing; so we matched up 4.5 Project X shafts. The result was what I wanted and I like the new feel. Able to do more of a straighter, Dufner type ball flight. However, I totally lost the feel of my sand and lob wedges with their steel shafts in the process. The new set had included the gap wedge and I was shocked at how much longer, straighter and easy I could put bite on the ball. So I went back and ordered the other wedges with the same shaft. After playing them for a couple of weeks all I could think about was what an idiot I was for not doing all of that sooner. I will be adding a couple of hybrids to the equation very soon.
FWIW if you want better feel in your short game and are doing what I did.
