Liberty got a bit of a bad rep from the first skis they made; but in the last 3 years the quality has skyrocketed, and the bamboo core is awesome; however a lot of people stll rate them on the first couple of season's skis.
The Genome will be one of the best big pow skis out there IMO, light, 140 underfoot, with full rocker but standard camber and sidecut underfoot so you can ski it on piste as well.
I think that they are a hell of a lot better than some people think, and not known about as much as they should be, therefore underrated.
