I've not used a first-gen DA FD, but I have used a 7400 and a 740n -- either 01 or 02; I think it's the latter. Again, it shifts very well over a 44/28 and also did so ove a 38/24.
Now, I may simply be less demanding about FD performance; and I don't shift the front a great deal (my setups since the 2X9 on the Fargo are 1X + granny) but when I do shift the front, I don't have any more problems than I had with more typical road doubles or old-time mtb tripls. I do have a chain catcher mounted to the chainstay just aft of the bb to prevent chain suck, but I first installed that on the Fargo with the 46/36/24 triple when I was having chainsuck problems; I've not had that problem with the 2Xs. To sum up and answer your question directly re the 1st-gen DA FD: I guess it will work fine. But if you ask me in court, I'll deny everything. Good luck! And keep us informed.
