I have played golf over 25 years and have tried many different putting strokes. And from my personal experience and from observation, long putts should be more flowing, (armsy & wristy if needed be) and athletic and less mechanical vs. short putts should be shorter back and through with firmer wrists.
For the long putts, I like Ben Crenshaw, Tiger Woods, Phil Mickelson, Brad Faxon, and as Stan Utley teaches; open to close and an arc.
For the short putts, I like Steve Stricker, Snedecker, Lucas Glover as Dave Stockton and/or Dave Pelz teaches.
Please share your thoughts. Thanks.
