I have my Quickbeam's front CR720 yoke set up fairly high, and with Koolstop or Yokozuna pads. The original "crappy" Shimano low-profile cantis had the yoke almost resting on the M12 rack's center post. So maybe a 2 inch difference? Just measured - my Tektro CR720 straddle cable yoke is 6 cm above the rack mounting hole on my green OG Quickbeam. Until I raised the straddle and changed the pads, the Tektro was far worse than the original brakes. The rear CR720 simply got replaced with the Shimano one.
My rule of thumb is "low profile, low straddle, high profile, high straddle." I don't think it stands up to the geometry science, but it seems to work okay in practice.
