this. Msnow is sick. it's fast, but you can still keep control on it, and more importantly push sideways off of it for hopping on lipside. otherwise you can use plastic lattice fencing. it works too, and its a lot cheaper, but its like skiing on sheet ice.
One warning: Msnow grinds the shit out of your bases very quickly, so find some cheap beater skis to use on it.
