There are boards that are equal or better for less money. Both boards are fun, I've ridden previous years models. The attack banana is a much better all around board than the skate. But they don't have as much pop or pow float as what I'm riding now.
If you are riding east coast ice the magnetraction is definitely a factor for you as it does help on hard pack. Where i am on the west coast it really doesn't make much difference.
Currently, Im riding a K2 Turbo dream and a Salomon Villain. The turbo dream has similar pop (maybe a little less) but much better powder float, and a hard to describe "smoothness" to it, everything is just smooth. The Villain has about the same float and edge hold and way way more pop off of jumps and side hits. The base's on both boards are also faster. If I could only have one board i would probably go with a Salomon Assassin, but i haven't ridden it.
those two Lib techs are still good boards with cool graphics and made in the USA, if you like them get one, you probably won't be disappointed.
Dude, suckin at somethin' is just the first step to bein' sorta good at somethin'
