A good friend rode a Cervelo with SRAM Red on it. That bike resonated just wrong with the SRAM and was loud as all get out. Perfectly adjusted, but you could just hear everything like it was a sound board for the drive chain.
You can't really mix 10 and 11, you'd have to move the cassette, but a true 10 speed hub won't usually fit an 11 cassette.
Other way around is ok though.
