I'm been on the devastator all season and i love it. shreds everything from groomers to pow. they are surprisingly quick edge to edge too. check out the review blister did for them. i havent taken them in the park aside form hitting some jumps, so i dont really have any input in that regard. if your looking for a hard charging, stable ski that you can ski every day, i would definitely recommend them.
