I don't hunt out of anything else now. It took some time to get used to but I have always been a very mobile hunter. I scout and then hunt constantly. I walked over a mile today scouting toward my afternoon set up, that I had scouted last week. The positives out weigh the negatives once you figure it out and how to implement it. I can scout super thick cover, couldn't do that hauling a stand. I can get in almost any tree.
I do not use sticks. I think that defeates the purpose for me. I'm packing a Shikar from Out on a Limb and use it as a one stick. I have about 60' of rope and I rappel out of the tree when I'm done. Setting up takes me about 10-15 minutes depending upon the tree I'm climbing. Getting down and fully packing up takes less than 5 minutes. If I think I'll hunt that tree again I will leave some paracord up so next time in I pull my main line up and then use a hand climber to ascend, which only takes a few minutes to be set up.
Unless your already have a stand set up this is the quietest way to climb a tree without a doubt.
My whole set up weighs probably less than 10 lbs
I actually gave my neighbor my climber to use this season because I have not used it in several years.
