I put a fat grip on my putter in a desperate attempt not to be the worst putter in history. I kind of like it. Shotscope does a far worse job recording my putts than when I had a regular grip. I bought the putter tag pack, but it still only gets it right about 1/2 the time.
A few rounds ago, I tried manual putting mode. You click every time you putt and then once where the flag is. I like it better. I think I’d use it even if went back to a regular putter grip.
So if you’ve never tried it, you might consider manual putting mode to see if you like it too. And I have a couple spare putter tags (one sticky and one threaded, I think) that I’d send you if you are in need of one.
