Ya, it sucks that you now have to use the ski manufacturers in house binding in order to use their skis. It has kept me off of a few brands of skis.
Never been too thrilled with Burtons non standard mounting systems either. I've used their soft boot boards up until now and bitch to the rep every time I have to mount up a 3 hole system. Now that it's a track, well, time to find another board manufacturer. We're not their target market anyway so I'm sure they don't care if we use their stuff or not.
