Occassionally when putting I feel that my take away isn't staright and that the club head is all over, this results in the putter head not being square when I hit the ball. I've tried tucking my right arm against my body but I still don't think its coming through square. I'm a 5 Handicapper, my tee to green play is usually very good but 99% of the time I 2 putt. Any ideas how I can develop a better putting stroke?
