I originally bought the Head Radical 260 MP back in high school and I had a hard time hitting with it due to switching from a racket with a larger head size and more open string pattern. After not playing at all since 1999, I broke out the racket again to play with some friends and maybe due to the long period of in-activity, but the Radical 260 finally feels right in my hands. From the baseline, I can drive the ball really well. Admittedly, my backhand is the better of my groundstrokes, but I can really wind up and unload with it more than other other racket I've demo'ed in the last year. I usually try to play at least once a week over the last 2 years and I've grown comfortable enough with this racket that I picked up 2 more on eb@y. Chances are this will be the only racket I'll ever play with, no matter how much people tease my racket looking dated.
For comparison purposes (and peer pressure), I've either demo'ed or bought every Radical that's come out and the Radical 260 still comes out ahead for me, although the Radical TT and Radical Ti are probably the next best ones I've hit with. The Radical TT, while the same mold, still causes my forehand to sail a bit more for some reason. I also don't get the same amount of touch. However, I do prefer the 2nd generation TT over the 'zebra' model.
And over the last few years, I've also played with the PT280, the Vamp Tour, and a cut-down Tour XL, and they all play differently from the Radical 260. While the PT280 is probably more popular, I've found the racket to be too soft. The PT280 has a huge amount of flex compared to the Radical 260. The Vamp Tour and the Tour XL just feel noticeably lighter when hitting compared to the Radical 260. If it weren't for the novelty of having similiar-looking rackets, I would probably sell them off.
