I am leaving my RDX 500 for the Pure Storm. I just ordered two of them. I've demoed about 10 frames over the past few months and the Pure Storm was the only one that gave me similar or more control and less weight. Very nice frame. The more I hit with it the more I like it. It's good for spin, excellent for serves, volleys well, and feels good when swinging out on both wings. It's just a solid all around frame. I played a near perfect 3 games earlier today with it, winning 11 of the first 12 points of the set. No errors, and about 6 winners. I think I hit my fastest serve ever today as well. I would guess it was around 130mph. The ball clipped the returners frame and shot about 50 feet out of the court. He was lucky to get his frame on it at all, but it was hit fairly close to him so he didn't have to take any steps, just move the frame. The other thing that surprised me was the contact felt good. When I hit that hard with my RDX 500 it rarely feels good. There seems to be less shock on the Pure Storm even though it's a little bit stiffer. I've read on the boards that there will be a cortex update to this frame, but it seems pretty sweet the way it is. If you're looking for an 11oz. control frame this one is worth a demo.
