If you want some cheap hydros, Shimano Deore hydros are amazing for the price. They're a bit heavier than Shimanos higher end offerings, but lever feel is identical and power and modulation are very, very close.
I'm interested in the IRD Dual Banger mech discs, but havn't tired 'em, and don't know anyone who has. Instead of just moving one of the pads, and thus pushing the rotor into the other pad, like every other mech disc that I'm aware of, they move one pad, as well as the mounting tabs. The tabs move half as far/fast as the pad. The result is that, in effect, both pads are moving together. Seems like a really good idea. That said, I have absolutly no experience with how well they actually work. I'd love to have you be the guinea pig on this one.
