I recently went all Titleist with 910's (D3, F, H,) ap's, wedges, and the newport Scotty. Love them all! One thing I'm not thrilled about is the F is starting to look much older than the one month I've been using it. Anything above dead center leaves a mark and it's looking terrible. Anyone having this problem? Is it normal? My old 15 (cally) was used for 3 years and didn't have a mark on it?
