Wanted to see if you have heard of or had any opinions on the directed force putter? It claims to be lie angle balanced and will not rotate off the lie angle once the stroke begins. They have a little gadget they use to demonstrate how much normal putters and normal face balance putters rotate all of the place without conscious hand control. Just wanted to see what you thought of them.
Geoff.... good to see your interest in Directed Force Putter with this posting. I trust my past comments were also helpful in your analysis of this new putter, namely:
Geoff…. what is your opinion on the DF Putter and the claims made for SBST putting stroke jig to demonstrate the putter stroke stability.
Here are the four YouTube videos made by Bill Presse, the inventor and owner of the company:
Introducing Directed Force Putters
Putter Arc Demonstration
PressGrips - Integrated Forward Press Technology
Remote Fitting Instructions
Also, here are the Presse patents for the DF putter and grip for your information:
8,932,148 -- Elliptical golf club grip
9,233,280 -- Self-balancing putter
IIRC, you are or have been involved with a putter company for design advice. The DF putter looks interesting based on the claims. Thanks.
