There is no difference in the BB on either a compact or stand crank. Smart move dump the fsa the are no good compared to the Shomano. You can find a 6600 crank and BB on eBay for less than 165$ I am sure. It will work as well as the 6700 you save cash. You swap out the crank in less than 20 minutes. Compact or standard no difference in the procedure just in the FD set up.
