Best racquet switch you ever made?
What was the single best racquet switch you ever made, and why?
Usually on these boards people are making what appear to be horizontal moves - going from one frame that suits their game quite well to another that is a little more powerful, a little more comfortable or has a little better feel. But have you ever switched to a new racquet that immediately made an impact on how well you play and how often you win?
Please name the frame you switched from and the great frame you switched to, and what is/was so great about it.
(And, if you've since moved on, please tell us what you next switched to and what the hell you were thinking by moving away from a racquet that you played so well with!)
