Scotty Cameron Art of Putting - Toe Flow
If your stroke does not track along the proper arcing path,
choose a putter that helps correct it. If your stroke flows naturally, choose a putter that flows with it. This will reduce the tendency to manipulate the putter face with your... hands. The best way to find the toe flow that corrects or compliments your stroke is to hit straight, flat putts from 20ft to see what works best.
