Had been cross-handed for ten years prior to my last round last year at DS. I decided to go back to a regular grip based upon a practice session the day before and earlier before the round.
Had 32 total putts. Four one putts and no 3 putts.
And Best of all.
The FGI Championship with my partner TheVinman.
And playing with Weirfan and just enjoying, at least from this FGI'er, one of his most surreal rounds he has ever experienced.
Not saying to not experiment with cross-handed putting, but look at a possible flaw in your conventional style.
I think I found mine. But it doesn't mean that you can find yours. Cross-handed is not a flaw. Just another way.
