Need to replace my Dura Ace front mech, is it ok to use the latest 7900 front mech with an older 770 Groupset?

Should read an older 7700 Groupset not 770

I'd be careful. I know the latest 105 front mech is not compatible with older 105 (or any older shimano) shifters, so I'd double check before buying...

EDIT: done a bit of a search, and it looks like they changed the pull ratio for 7900, so not compatible...
