Which front derailleur?

I'm trying to find a useable fd for an odd bike:

Triplet frame, 559 wheels, 53, 42, 30 front chainrings, top-pull
derailleur, 68mm shell, 160mm rear spacing. I prefer a bottom swing
since the shimano top swings i have tried give unsatisfactory
performance.

Suggestions? I see some SRAM products that may work, but i am not sure
if the cage shape will work with the chainring sizes.

Thanks,
Blake

what type of chain? what shifters?

I use salad tongs on the front. The universal shifter.

On the internet, nobody knows you're a jerk.

Got room to install a pulley onto an 'eclamp'? Onto the seat tube?
