What would be the point, if you're going to have a different chainring and chain? I mean, I know they're probably good cranks, but to use just the cranks with everything else different? I would just save the cranks for when you're going to run the whole setup, but that's just me.
People have asked about the 10-pitch chain around here, it sounds like you will be watching ebay for a couple years and dropping a lot of dough when one shows up, unless you find one in a dusty corner of a bike shop.
