I'm in my fifties, play only doubles, and currently own a Roddick Plus and an O3 SP White. I love serving with the Roddick but find it sluggish for quick exchanges around the net. I also like its crisp feel. The SP white is just the opposite. Its great around the net but its just an averege serving racquet and I also find it a little too soft and lacking feel. I was thinking about buying the standard length Roddick hoping it would be more manueverable, or the Ozone Tour (not the pro tour)because reports on these boards say it is crisper than some of the earlier O3 frames. Has anyone whose used these frames for doubles have a comment or suggestion?
