I think, if it were my bike, I'd change the FD shifter to friction (bar-end, perhaps), so you'd have a simpler time of chosing either "here or there" and instead of futzing around wth "trim" you could make those minute adjustments manually. It would also end the problem of accidentally shifting whilst braking.

This is something I'm looking into, myself, as I hate the brifters (I have little kid hands). I have massive problems with accidental shifting while braking, and sometimes can't tilt the shifter lever over enough to shift properly.

Brifters may well be wonderful for many people, but for some of us, they are a bad match.
