Geoff,
I understand the principle of the fixed pivot, and as I understand it, you say it is the most important factor in straight putting (right?). I understand the concept, however, how to perform it is a different thing altogether for me (maybe I am a little deficient in the learning department). At any rate, are there any good drills or aids to help in the specific learning process of keeping the pivot point fixed? Do your drills listed under straight putting on this website apply to the pivot, or is that a totally different thing altogether? Thanks for all your help and for maintaining the best golf website there is!
