the white, then orange 1260s were symmetrical. as far as i know, there have been no other symmertrical skis since, until the invaders came out, and now the addict and atomic urban triplets. the mad trix were not symmetrical, although the current ones are mounted at center. the 1080 was never symmetrcal; they just flipped the graphics to try and make them look cooler. as far as line's pattent, i think it could definately be enforced. is fischer actually going to sell enough pairs of addicts to make it worthwhile to line? probably not.
