SX-11 tuneMarmot- High end Atomics are 3 & 1. A straight 0 or as we say 90° Is a right-now edge. You lay over and your edges are right there. This is good for slaloms. 1° base bevel is very forgiving, less likely to 'catch an edge'. Most skis are 1 & 1 or faily close to that. volkls are 1&2. 1 on the base and 2 on the side.
3 & 1, 3 being the side bevel gives a very sharp edge to present to the snow. This is good for good edge set, sharp turns, ice. If you like this, keep it. If you like the 0° keep that instead. It's your personal preference.
Every shop is different I guess. Yours sets at 90 if nothing specific is requested. The guy who used to tech for us and now is head tech for a competitive chain of stores, sets all at 1 & 1 unless something specific is requested.
I usually try to keep the ski's bevel as they came from the factory, most of which are 1 & 1, but some differ from that as teh Volkls do. K2 comes 1 & 1, but I redid my Mod X's to 2 & 1 like Volkls. I"m enjoying them that way.
Try them each way and decide what you like. Don't do this too many times. You could end up with no edges at all! That would be a bit of a bummer for a fine ski... and wallet. And above all, wax at least every third trip up. Bob
