This is more of a safety tip than anything else.
The other day I was climbing, actually clearing up from sleeping in the trees and in the process got caught in a heavy downpour. I backed up my descent device with a munter and ended up getting some twist and tangle from the throwline I was trying to leave in position in the tree for others. When I got to the ground and tried to pull my cinched anchor, for whatever reason, it would not budge. I planed on going back up to check the line but could see a potential fatal error for anyone needing to return for a cinched anchor.
Scenario: You get to the ground, remove your climbing device and start pulling out your climbing line, you tug, reposition, stand back to see what the problem is, return and pull some more....SOMEHOW, IN THE PROCESS YOU GET THE LINES CONFUSED and don't realize it, by mistake connect to the tail to re-ascend, 50' up it finally lets go....
Solution: I will never climb up to free a stuck canopy anchor without putting a friction hitch on the "other" leg even if I am 100% certain of which leg I'm climbing on. It is easy to install and self tends soon after you leave the ground. Another solution would be to never having two lines in this position by using a throw line for your recovery leg. Personally, the tail is the DdRT system I later use to traverse or progress past my TIP. I also often reset the TIP as I move to other trees or move up.
