Went by my local PGA Superstore and saw they had a demo program, so I grabbed two rackets and hit for about 90 minutes on a ball machine. I tried out the Prince exo3 Rebel 95 (the Monfils) and the K-Six One Tour (the Fed). The Prince was really nice, but felt a little spongy on impact. While it was a heavy racket, it had a low swingweight and I wasn't generating a lot of power. Plus...it's just kinda ugly. If I hit great with it I'd look past that, but since it wasn't awesome it was easy to pass on. Not the biggest Monfils fan, either. So I tried the Fed. The 90 inches scared me a bit, also the heft. But I hit GREAT with it. But from what I've been reading, you have to possess a technically sound swing to be productive with this stick. I'm probably a 3.0 (3.5 on a good day). In the heat, after an hour I was really dragging. I decided to try serving while a bit worn out. I was amazed by how effortless I was swinging and still hitting good serves. My serve is my strength (or as I call it, my crutch), so I was pleased to see I won't be losing anything if I decide to go with this racket. I wasn't getting much elbow discomfort, either...which has become an issue for me. I want to hit with it a bit more before deciding to buy, but I'm shocked that I demoed this racket on a whim and am now considering switching to it.
