holy retardedness. and i believe i recall the thread your talking about jib. i love k2, but hate them for making up their imaginary 'core center' to confuse the ever living hell out of every person who can't realize that its just a proprietary number on the side of their ski that at one point, had a meaning, but not doesn't mean anything at all. in the past, a la the first gen. fujatives, you weren't supposed to mount the skis past that line due to the reinforced binding mat. now, it doesnt matter, you can mount them at center just fine, so core center doesnt mean crap. its not the center of anything at all, actually.
