I've had the Ghost Spyder ever since I hit level 35, loved it, 'upgraded' it at level's 66 & 92, but with the free rental weekend thought I'd give the Versa a shot as I'd heard good things about it on champ speed greens.
Tried a couple other putters as well during the free rental period (are you listening WGT?) but there was really no doubt in my heart from about the 3rd or 4th hole that I'd get the Versa. As SB has already said, longer putts are falling far more regularly - don't ask why, couldn't say, just know they are.
As to the question of if it's worth 40 bucks or not, well.......but personally I'm not 1 bit sorry I bought it.
Now off to watch more ad's to pay for the dang thing
