ˆ 5700 or 6700, but no real benefit to going 6700 unless you can get a deal on it. Either should be pretty cheap

I can't see any advantage in replacing a 5700 front derailleur with 6700. Functionality is identical.

Thanks for the help. I am finding very similar pricing of 5700 and 6700 front deraileur. I will go with the less expensive 5700.

7900 is by far your best bet, far superior to the 5700. Much stronger and sturdier creating crisper and better shifts.

Not sure it will make any difference.
I recently got my old 90's Bianchi back on the road. I replaced the old worn out Campy Ergo's with some NOS 7700 (9 speed) STI's that I had laying around. I had a good rear derailleur, chain, wheels, and a few cassettes, but I only had a clamp on 7700 front derailleur, not a braze on. The only braze on that I had, that was not being used, was an old early 80's Campy Super Record, made for friction shifting. I thought that it could never work with an indexed system, but I gave it a try.
I was shocked that it worked perfectly, and that I could even shift out of the saddle.
Maybe I just lucked out, but I've done things like this before, and they always have worked for me.

Proceed at your own risk.
