I bought a bike with ultegra hydraulics, and they feel nice and all, but I've heard that bb7's are almost as good. Is this true? I'm thinking about down grading to 5800 shifters and bb7's, and sell the hydraulic lever/brakes for around $400 (they're pretty new), reason being my race bike has 5800, and it would be nice to have that cross compatibility. in addition, it feels weird to commute on such a fancy bike, like even fancier than my race bike. but then again, hydraulic discs seems to be more future proof. what do you think?

actually after looking on ebay, it appears $400 is very optimistic, and I'll only get <$100 savings after shipping and transaction fees. so screw it. I'll just have to crash less often
