I'm a bit inclined to see a particular truth in Bellafonte's line of thinking only because I don't think I'm experienced enough to know when frame material is fatiguing me 🙂 AND a particular brand of logic concerning carbon fiber would seem reasonable as even the most uninformed know that carbon fiber is not metal and metal surely must be harsher than something non-metal 🙂
In any case it is a marketing man's dream material...
and in addition to all that, Bellafonte, I like the Banana Boat Song... :P
