the magna-traction system is weird... the edges are wavy to give the ski 7 points of contact on hard pack snow or ice which cuts into it better... they better work for how much they are...
invaders have a pretty sik design and shit... but they're such a crappy ski... they dont last very long. i heard next year's are gonna be better tho...
ssiiiiiikkkk... best ski i've ever been on. they're pretty stiff but after a month or two of skiing they soften up... like almost any other ski. they still have hella pop too tho
