TRP Cable pull hydraulic calipers question

[Steve vRS]

I’m looking to buy one of these for my CX bike. http://www.wiggle.co.uk/trp-hy-rd-cable-actuated-h... . What low compression cable would you recommend to use with it? I only need the one as my front brake is great but the back caliper is grinding and not springing open fully plus the long cable run doesn’t appear to work well with the mechanical disc caliper in my opinion.

Thanks in advance!
