Get it fitted.
Here's how
clubs work:
Either you adjust the club to your swing, or you adjust your swing to the club. It's that simple.
That said, a lot of guys on Tour use Yes! putters, and aren't paid to do so.
I was considering a Yes! Tracy 2, but ended up with my MentorSports Triad 2 instead (and love it. It took all comers for the bag this year).
My regular playing partner has a Tracy 2, and it makes a weird sound (to me, like a 'corking') when he hits it on center. Mishits are muted.
But Greg makes a great point - it's gotta fit your eye. A lot of people hate the size of my big blue monster... but you can't complain when I'm tapping in for 2 putts, early and often.
