To a degree I agree with Jimbo about your game play . You need to work on your short game and get closer to the pin ., But at the same time you still have to be able to putt . If you decide to upgrade your putter then get the 96+ Versa putter . Its to be the best putter in the game for both putting styles .
Sometimes when putting you will have to move the marker in order to help the putt hold its line . The Versa is great for this when needed . Play some practice rounds and use the rock to work on your putting . You have the clubs that you can use the rock and still hit good shots . In fact the rock is not only my practice ball but I will play rounds with it as well
But get the Versa as it can easily be the last putter you will ever buy .The only way that I will give up my 96+ Versa will be if WGT puts a newer one in the shop that performs better , if thats possible . Good luck with your game and hope this helps . :-)
