Good idea Chris - I don't know much about SRAM. I am gradually switching over everthing to Campy so at least when individual parts break I can repair them. I think it's important to remember that component companies don't usually design each line independently. They design the VERY BEST for racers - Dura Ace, Super Record, etc., and then they cut corners to get the cost down for the lower component lines. This is also why features trickle down and last years Dura Ace is this year's Ultegra, etc. I can't wait to at some point have an all Record or Dura Ace bike to test my theory, but given current cashflow, that will be a while.
