lots of miss info in this thread. alot of top sheets chip around the edges and alot of that is the rider fault from banging there skis together constantly in the park. but ya lib tech seems to have a small problem more on the topsheet they used on there snowboards. seen those peel the skis just seem to chip around the edges. you will not notice the magna traction on rails period and one saying they do is insane. you will notice though on groomers as they rail turns even with your edges detuned to shit for rails which is the ultimate advantage to have libtechs for park. i have the 178 free rides and they are the nicest pair of skis i have ever ridden. they make four skis that would honestly be the perfect quiver, pipe, jib, freeride, pow. my neighbor who has both freerides and pows and loves them also. everyone i have talked to in tahoe that has some libs has nothing but good things to say. the only downside is the price, but they are quality skis made in the US by the coolest company in the game LIBTECH. Ow and they make a mono board.
