I have been using a set of leverage climbing sticks for three or four years now. If anyone knows of a set that is for sale please let me know. I'd love to get another.
I'm glad this tread is up. I want to modify mine so that they can be affixed with a rope cleat. Here is a youtube video on how to do it.
Last year I came across a Loggy Bayou hang on stand. It's as light as a lone wolf, bigger, more comfortable and super easy to set up. I also have two loggy bayou climbers. I have one with the band and one with the cable. Both are awesome (except for the climbing aid which can get tricky at times). However, climbing trees in a climber is really hard on my lower back. It's a lot easier for me to get up a tree with the sticks.
