I've got some rs685 shifters and would like to know if they're compatible with any post mount 160mm calipers or specifically only compatible with the rs785 caliper? Many thanks

Calipers should be fine as long as they run on the same brake fluid system(i.e. Shimano mineral oil) so don't put any calipers that requite DOT fluid, but personally I stick with the RS785 and R785 (I run the same levers, but for frame clearance I have to run a R785 in the rear and a RS785 up front, no issues whatsoever.
Thanks. What were the frame compatibility issue you had? I thought they were both most mount? As I can't find rs785 callipers only for sale I was looking at getting some different post mount callipers.
For roadies, hydraulics seem to have a bit of an aura of magic. I have little experience, basically I only fitted/shortened one hydraulic line, but it seems to me there is no reason why you can't mix and match, as long as the brake lever pulls enough fluid to push the piston of a given caliper, you don't mess with fluids too much and you get the connections right.
As I understand it, the difference between the R and the RS versions is the pipe entry and the bleeding system. On some frames, the R version (if I have that the right way around), gave minor heel clearance issues.
If you have a dig around you can find Shimano's product compatibility charts. Here's a link to their official compatibility setup for the hydraulic levers.
I have RS685 shifters and have just replaced my RS785 rear caliper with a T675, apart from different pads and half the price of the 785 it works fine, if not better than before, I have less lever travel. http://www.chainreactioncycles.com/shim ... prod119959

According to that, your rs685 shifters will work with the following calipers:
BR-RS805
BR-RS785
BR-R785
BR-RS505
BR-RS405
