I used to triple putt everything, regardless of type or price of putter.
The price for enhancing my putting performance was:
- get some sessions on a SAM lab or equivalent
- practice, practice, practice .. blood, sweat and tears
Having shin splint problems too at the moment. Go see doctor, and he will tell you:
- take NSAIDS
- coat of flexium gel (or stuff like that) on your legs at night, wrapped in plastic foil...
