About 5-6 years ago I purchased a used Scotty Cameron Squareback (2014) putter and loved every second with it. The weight and feel was perfect it seems. A couple of years later, I had decided to get out of golf (mistake) for a little bit and sold it. For life of me, I cannot remember what weights were in it. Fast forward to this year, I decided to give up my Odyssey PT82 putter because I was just not happy with the consistency/feedback I was getting. I searched for another Sqaureback (2014) and the prices are still pretty high. I ended up going with the upgraded Super Select Squareback 2, I found one for a steal. Finally I got the feedback I was looking for, but the weight just isn't the same I think?. It currently has 15g's installed. My question is how do I know when I need to up or go down in weight? Is it easier to just buy a bunch of weights and test them? Should I just keep the current weights and practice more putting? What weights is everyone else running?

Thanks!
