I've putted cross handed since I've taken up the game 18 years ago, started when I was 21. I never got comfortable with a " normal " grip, and tried "claw" and " pencil " style. Not alot of people I golf with putt cross handed, and I get alot of people thinking that I only putt that way because I'm a poor putter. I'm not gonna say I am a great putter nor a horrible one. But, I only putt that way cause it is the only grip I can be comfortable using. Anyone else out there feel the same way. BTW, my oldest son putts cross handed, and thinks the same as me, however, my two youngest sons are the complete opposite.
I have seen a couple of club members who play cross handed, OMG, I couldn't imagine even trying that, lol.
