Unless they've changed something in the past couple of years, the Hylex RS are available in both flat and post mount, front and rear. I think the Disc Trucker has IS tabs, so you'd definitely want the post mount versions. I believe they come with IS-to-post adapters for 160mm rotors.

One thing I like about Shimano calipers is the bleed nipple design which makes opening and closing the bleed port easy. There is no tiny screw to lose, and when you're done you can close off the system while the syringe or catch bag is still attached, with no chance of introducing air back into the system.
