SharpCat: balance (note sure what the means in relation to this game)
That is a most important, often overlooked attribute. Balance in a putter goes to the tendency of a putt to wander off line. More balance = better roll to the cup.
Imagine putting with a balsa wood putter. Light as a feather and difficult to keep from being deflected by the ball. Compare that to a well balanced putter where all you have to do is hold on as it swings an arc through the ball.
I have always thought the Versa was a Rossa on roids that WGT put out to lure Rossa owners (just like you) away from one of the most solid putters in the game. I use the #1 which I switched to from the 92 Ghost because of the increase in the balance attribute. Fixed the 8-12 foot headaches for me. :-)
