I've been satisfied hitting w/ tightly strung Volkl Catapult 10's this past year or so. But boy, when the string tension starts to loosen up, the catapult's "trampolines" kick in and make it more than a little unpredictable. That's when I reached into my bag last week and pulled out my old C-10 Pro, rather than my spare Cat10. Heavier weight and more flex, naturally, but I drove through the ball, hit deep and served wonderfully. Still (re)adjusting to the weight, I was a bit late on some volleys. But overall, the switch back to an "old love" felt wonderful. I gave up the C-10 last year for a lighter Volkl because I felt it lacked maneuverability and I was often swinging late on service returns, etc. But either my mechanics have improved since then, or I'm (finally) learning to shorten-up on my backswings. Think I'll stick w/ the C-10 this summer (unless I'm tempted to demo the new V-Engine 10 MP!). Anyone else have experience returning to a once-beloved stick that had fallen out of favor?
