First question: Ultegra 6600 brake calipers... how can I tell which is the front and which is the rear... they look identical other than the direction of the pads... or does it really matter? I saw a pic of a bike with the same calipers and the 'fin' on the pad holder was facing backwards (well, it looked backwards to me) so I don't know if that's correct or not.

2nd question... cable package... two types of cables supplied, kinda of confused as to which is for what. I think I figured it out, but wanted to double check. I know the short cable housing is for the RD, but I guess what's throwing me off is the thicker cable already set in their housing.

Unfortunately the frame doesn't get here until thursday... arrrgghhh!!!

Thanks for any help!
