all you need to do is make sure whatever you get (which should be a look or rossi) you get it w/ wide brakes, so you don't have to bend them, which w/ karmas i guess wouldn't be too big of a deal since they aren't that wide, but for a newb. its just easier. You should look for last years axials, if your kinda light, get the 100, if you weigh up to like 200 get hte 120s, and if you ski hard get the 140s,
