It's been promising. Have about 3 rounds in it so far, first one was a learning experience, second was good, then didn't play for 6 weeks and had forgotten how to use it. So much is in my head when I stand over that sort of shot, even when I'm thinking "just put a putting stroke on it". Just need to find a way to lock in that short bump and run with it (putting stroke) and it might save my game. Of course practice might help.
I find that 90% of all my shots pull up short too so when it doubt, hit it a bit harder
