Been using these drills for several weeks now, and studied your videos.
Results are amazing! In the last 3 weeks I have played 8 under my previous handicap (for nine holes within my league). I have data that can prove results. At my age 61, my handicap is 4 strokes lower in just a short time.
My practice sessions are very focused, since I sense and feel want I am doing works.
Only wish I had more golfers using your techniques up here in New Hampshire and Massachusetts. That would make practices even more focused and fun.
