Reach, I use the Trango and I think you will not be disappointed if you decide to try it. I think it has plenty of potential for a clever fellow for it to be utilized in many situations and manners. It is well made and simple. I got it primarily for experimenting with a really long flip line/secondary tie in. I use 20 ft of Bee-Line. It does what it's suppose to but truthfully I have found in most situations if I need a secondary tie in point, I would just as soon use a climbing line and as far as using it for a flip line goes, it is super light weight. The kind of thing you would use mostly on small diameter wood (high in the crowns).

I just got a trango cinch to try out and wanted to post some thoughts in terms of the cinch as a lanyard adjuster.
Very clever gizmo, and in general grabs very well and gives lots of control for releasing line. Rated from 9.4 to 11mm but seems to work okay on bluemoon which is around 11.7.
I got the cinch to try it on my second lanyard (a 11mm 20 footer that I sometimes carry) to go along with a shorter lanyard I carry with a knut. I liked the idea that the device was "shorter" on the rope than a friction hitch.
The one thing that makes me a little nervous so far is that if the cinch is restricted in it's movement (can't swing forward) when it has no load on it, the line can run freely through the device without ever catching.
It needs to be able to freely swing forward from the climber so it can grab, and I can image situations where I am against the tree or branch and the device wouldn't grab.
It was designed as a rock climbing belay device, and for that the belayer holds the device in front of them with the flat side to the side, so the cinch is hanging off the carabiner with the rope through it. Thus a pull of the rope and the cinch can swing up and grab.
I like the control it gives, but so far don't quite trust it like I do a friction hitch. Also there is the issue that the release lever has to swing out 180 degrees to release tension and that can be pretty awkward depending on which side you run it on. (It was designed to be clipped in in front of a belayer.)
All in all, hard to beat a friction knot of your choice (like a knut with short legs) with a micro pulley. Compact, works on left or right side and pretty foolproof.
