notcold: I think I'm a fairly good putter but regularly 2 putt holes missing the cup by inches.
The balance attribute is going to do as much for this as the precision does. Balance is the putter's tendency to hold a line, particularly on longer putts and it sounds like your putts are wandering off the line.
IMO, going to that Versa is a great move and would be willing to bet you see an immediate difference. I have the 97 version and swear by it. :-)
