I ride a Never Summer SL
There were a couple of days with flat light, and wind scoured patches of icy chundra, where I felt like I wish I had something heavier, and more dampening, else everywhere, every day, I felt confident and in control. Its close to a twin tip, does not feel awkward switch or jumping, and I am confident on it, regardless of how steep or how fast.
It is, thus far, my favorite all mountain, all conditions ride.
I rode many of the Lib Tech boards during demo days, and while I am grateful for the rocker/camber revolution they helped bring, the magna traction did not suit my style. It traverses as if locked in, but when wanting to accelerate hard on an edge, I always felt conscious of the drag.
I note, however, that I live in the Sierras, and snow (as opposed to ice) is pretty easy to find most days, if you know where to look.
I highly recommend demo'ing both the lib tech and the never summer, and seeing what suits you.
