I have along enough rope that Ican slide the puristic knotall the way to the end, and have plenty of room to move freely to whatever position I want! I make it so that when I'm sitting, it runs out the top of my coat,all the way to the seat, then back up the tree to just above my head(when sitting)!!If I fall, its going to be a few feet, but thats better than 20+!
I have friends that set it close enough that they can lean against their harness when shooting, but I find it restricts me too much!!
Get a longer rope!
