Looks pretty cool, good vid. However, we tend to over complicate things for very little gains. To me, and just my opinion, that is too much stuff to have in a tree. In a nice perfect crotch like that one, I am sure it works fine, put that in a tree that is very thick and grabby like a ash or locust or one that has tight crotches and all that stuff is going to get snagged on stuff and you will end up going back up after it. I have climbed off of my rescue pulley and then, right away, on my caterpillar friction saver, not hardly any dif in friction. With all these new gadgets coming out all the time, seems to me, by the time you get all that stuff set up and in the tree, I will be coming down to chip.
