Well, I can't speak to the Superfly specifically, but I do have the Mamajamba. I use separate tie-outs (as warbonnetguy recommends) but for a CRL, I'd go anywhere between 30' and 40' to be safe.
I'd also set the ridgeline over the tarp, not under, as the superfly has a slight cat cut along the top ridge to help keep it taut. Running the RL underneath will impede the way it is designed to work, I think.
I like the illustration Dejoha put up in a sticky in this forum, it's worth checking out.
For a CRL though, I'd say over the tarp, and maybe use the prusik loop method for tensioning at each end?
