6sp Front Deraileurs vs 10sp for shimano?

as per subject, I know the chain widths have obviously changed, but has spring tension or cable pull rate changed on these?

I am running an older shimano 105 FD with campy levers and it requires about 4 clicks to get into the small ring (one sweep of the thumb button), but to shift up to the big ring, its closer to 6 clicks.......... which means almost 2 complete swings of the shift lever..

If the pull rate decreases with new FD's would it help? ideally I'd like only 4-5 clicks for either shift..

I know i can just get a new campy FD, but many say that the shimano stuff works better?

It's not just the pull ratio. Nine and 10-speed front derailleurs have narrower cages and different shaped cage plates to go along with their narrower chains and chainring spacing.

Yeah, cage width was my first thought.

Are you saying that you have a 6-speed 105 FD? It would help to know more about what you've got. It sounds like you have a double crankset. The difference in chainring sizes can also effect how quickly and smoothly you can shift.

My Campy 10-speed double shifts up or down with 3 clicks.
