Excellent comments and I agree with those facts.
But the fact of real life is now getting on the table.
Real life or WGT I agree to pay for a better club and get better results.
But in real golf, if there is 1 club that it is stupid to pay for, it is the putter. Get one and play with it... You will get used to it and you don't change that... And you can get very good...
I am personally using the same putter since my Junior days. The putter of my first $100 Golf Set.
My Suggestion? That WGT provide a putter that you can get used to, and get better...
Actually it is ruining most of my games.
