Replying to Adjustable bindings?

So I was wondering if there is any bindings out there that are adjustable bindings that AREN'T for DEMOS. I haven't been around long enough to know all the stuuf about bindings. This will be my 3rd season skiing (not counting my years skiing as a kid). Just picked up some 2011 Line Blends, so im looking into bindings now, thing is I will be getting new boots next season probably so I don't really want to have to remount them. Any suggestions? Also I ski probably 90% all mountain and 10% park but plan on going more like 70/30 this season, MAX din binding I need is 12.
