Here is how mine are setup. Obviously red is gas, silver is oil. Paracord choked and taped in place, mini-biner on the loop to hang at what I found to be a comfortable level. The important part is the caps, with these little snap/swivel things, I can unscrew the caps in the tree while keeping them tethered so I CANT DROP THEM in the tree, but also allows me to unclip the cap-tether if I'm working on the ground, which makes them easier to take on and off when that isn't a concern.
