I agree with all the posts about the Ti.Radical. Head's attempt to reinstitute the Twin-tube technology in their newest racquets was to me, a poor attempt to replicate a classic! Their Ti line of radicals was IMO the best feel of any racquet they've ever made. I'd say the i.Rad even feels better than the new LMs. At any rate, I agree with a post someone made some time ago that said racquet manufacturers should just keep a good thing going and maybe change the paint jobs. My personal top five best feeling/hitting/performing racquets (in no particular order) include a mix of old and new:
Wilson HPS7.1 Zone - (Awesome serves, awesome groundies, avg. volleys, excellent drop shot)
Head Ti.Radical OS - (Avg serves, awesome groundies and volleys)
Wilson PS6.0 (85) - (Awesome everything!)
Dunlop MFil 200G - (Very good serves, awesome accuracy/control on groundies, awesome volleys, pretty good drop shot) - if enough folks start playing with this stick, it could become an "ESPN Instant Classic"
Babolat Aero Pro Tour - (I didn't put the same hours in on this stick as I had with the previous four, but this was a surprisingly good stick, notwithstanding it's higher than avg. stiffness rating. Good serves, groundies and volleys).
