The 11x2's were all non-finned iirc, it's the finned 11x2.5" drums that are super heavy. Not as much selection for drums and shoes for the 11x2's but they're out there. If you have all the stuff for 10x2.5" and not for the 11x2's I'd probably just use the 10x2.5's unless you're gonna run 11.75" rotors up front.
