After I nailed that 50 footer during 'the round', I told my friend "I'm gonna make a putter, for market, with a convex face, no indicator mark, the shaft goes in on a weird angle and it will be called 'Nemesis'.
I had tried several fixes- when I saw Bernhard Langer using a cross-hand grip, I found that it helped. For a while. Then, I opened my stance, which worked. For a while. The 'claw' and oversized grips hadn't come around at that time, so I just suffered and justified my suckage by saying "Getting to the green isn't the problem". Same putter through the decades, too- one of the main reasons for my thinking that it's not the club because it wasn't a case of it reaching its teen years and becoming rebellious. I went to a local course to practice and when I had basically given up, I tossed my putter into the air and when I caught it, it was with a right-handed grip, so I found a place to putt where there was no break and had better success. If I can make a straight putt, the rest isn't a problem because I can still read putts as well as ever.
I know someone who has a stand in his basement with at least 50 different putters. Can't get arrested with any of them and I would think the pro at his club is very happy about it.
