dura ace 7900 compatibility

[shotojs78]

Hi, just to be sure, I have a complete sram red groupo (except front derailleur) can I use a dura ace 7900 or ultegra 6700 with that, or just the 7800 version ??

or maybe I can use a record or chorus campy front derailleur with my sram?

thanks

Why not use a Force FD? Stiffer than the Red one and no question about compatibility.
