We have seen no wear issues with regards to the grooves. No sure anyone has hit more shots with the DRM wedges than I (we) have on sight and on course from a variety of turf conditions over a long period of time and we have not seen any groove wear. The DRM finish will show some wear over time, but what we have seen is minimal.
As far as what wedges I have, depends on the day and the turf conditions. If it’s dry and firm, I usually have the DRM 52 and 56 degree in the bag. Neutral to softer conditions, I go back to my M-Series + DBM 52 and 56 with the .090 sole width. Probably play the M-Series + more here in Ohio. I plan to put the MAX .090 52 and 56 deg. in the rotation if I ever have time to build them. As far as the other guys, Jim hasn’t played in a while so I would have to ask him, and I believe Pete is playing the MAX wedges in the 54 .090 and the 58 in the 1.05. He is out, so I will double check when he gets back.
