Not too familiar with golf swing analyzer software. I think video taping yourself and then checking for faults that cause your usual mistakes work the best for self analyzation. I assume any swing analyzer software requires you to video tape your swing?
Unless you can recognize your swing faults (and know how to properly correct them) the best "Swing Analyzer Software" is still a good teaching pro! Just askin...Do you think any software program would work for Lee Trevino's or Jim Furyk's swing? LOL
