On removals, being retrievable is a mute point. The concept of being lowered in case of an accident I like but i dont really sweat oo much about since I dont plan on being hurt and the alternative doesnt provide for that option either.
On a lot of trims, specialy where alternate lanyard acension is the best method, or where I run the risk f slashing my line in the brush, I just tie off at the top or run it thrugh the highest TIP possible and back it up through a few more crotches. (great advantage of SRT is the higer, safer TIPs)
To do a thorough prune job, you probably need to go through the tree once more anyway. Or at least I do. I also usually need to at least retrieve my block or pulley. The final decent I untie the running bowine and decend DDRT. Easy as my vt is already tied and ready.
Another plug for the leather tube cambium saver. Great for srt!
