The twin tube radical was quite a bit different. I got a preferred player sponsorship with Head during their transition phase from the older no gimic, "classic" construction rackets and their new "hi-tech" offerings.
Unfortunately...I bought in hook, line, and sinker into the "hi-tech" mindset of the day.
Much preferred the raw ball feel and assuredness of the Prestige Classic and PT280, which Head both still made available at the time, but instead went with the "twin tube" Radical Tour as it was kind of seen as the Babolat Pure Drive "must have" tech of the day.
This said, is the Radical Tour a bad racket? No, not really. It took me years after when I discovered this board, that oh wait, maybe the PT280 is a better racket.
In other words, this board DOES tend to bias you toward the more "old school" frames as somehow being better. (i.e. when I tried the Premier Tour out, I was drooling...thinking this is awesome and get this BETTER than the much vaunted PT280...now that the 280 years later is revered and almost kind of viewed like a "cult" classic, I think to myself how could I ever think that? So believe it or not, one person when he was in an *unbiased* state did NOT hate the Premier Tour, so sue me and throw a bag of chips at me).
Objectively speaking though, I would say that the Radical Tour is a FANTASTIC player's frame that offers decent spin, with pretty good control, good comfort for its stifness, excellent stability, and most of all very good get up and go for a player's racket. As for the zebra graphics, they were generally something you either hated or loved, but personally I fell right in the middle and thought it was (in my best Simon voice) "ok, flashy, perhaps a bit over-indulgent, but ok. If I'm being honest here, I don't think you're quite as good looking as you think you are (not saying I wouldn't do you though)."
On paper, I would say that the twin tube Radical Tour TRUMPS the PT280 and I think in most player's hands would help them out more in actual results. Where the 280 wins is for more highly advanced or fine wine sippers among us.
The 280 has that classic, aged feel. It's the kind of racket where if it's drizzling slightly outside, you'll feel every last rain drop and it's unique contours and sensations on your racket. With the twin tube construction, however, you'll find that it's a technology that really does do what it says on paper, but it has a tendency to make rackets feel slightly disconnected in a floating on a cloud of oatmeal sort of way.
You can never quite put your finger on it as everything's nicely muted yet crisp, flexy yet stiff, paradoxically in tune, control is good/power is good, etc. BUT you still get this vague sense at the end of the day that something's missing and everything's vague. Have you been drugged? You don't know, just know that you have no memory of what's just been going on for the last few months with the racket or so. In other words, in ONE word, numb.
There's just something about twin tube rackets that leaves you feeling less than exhilarated or enthralled and numb at the end of the day.
On paper though, I would give the 280 a definitive edge in terms of actual tangible PERFORMANCE aspects in one area only...and that is, ever so slightly, more control (which to your average consumer could just as easily be interpreted as this racket's underpowered and therefore must have a radical design flaw).
