This basically acts like a prusik and I can easily tighten or loosen the "loop" around each tree by sliding the taught line.
I've also played with the same set up using figure 9's in place of the taut-line knot which makes it a little easier, just more parts involved.
I think I might play with a CRL just to see if I notice a difference!
I'vev been using the method you're considering (with the fig 9s) for the last year, and it's been pretty much my preferred method overall.
