I've thought of adding a quick connect hook to the equation just to be able to do as you mention, get the stand where I want it and strap it in without having to hold the weight at the same time. Something I recently discovered which helped me is to have the strap shorter than the width of the tree where I can reach around and get the end of it and pull just what I need at the clamp and get it over the button, then pull tight. Before I would use the weight of the clamp and throw it around the tree and grab it, connect it to the button, then have to pull up all the slack. Inevitably the stand would drop a little and I'd have to readjust. I've only done it the new way a couple times and it has worked well. I think I'll still get a quick hang hook though.
I have a Lone Wolf Assault II with four sticks and the quiver. I bought the four sticks because the deal they were running basically had the fourth stick free, plus I'm on the shorter side. It also came with the quiver, which I used until recently. I found that with three sticks and stretching it out a bit I can still get up to 18' to the bottom of my platform, so I dumped the fourth stick along with the quiver which is more a PITA than anything. I'm thinking with another aider or two I may be able to dump the third stick and only need two, but that will be some trial and error.
Another issue was my backpack. I would attach my stand to my backpack and carry it that way. There are some straps on the backpack that I'd hook through the stand and connect, then pull taught, but when you unclip it, the clips are catching on the stand etc. I dumped that idea and just went with bungees through the stand and around the pack and it was much quicker getting attached and unattached, but I still felt like I was carrying the damn rucksack I carried in the Army, LOL. After a recent hunt I got home and pulled everything out of the backpack and looked at how much space it would take up. I bought a butt pack with harness system with a waist belt, that allows you to remove the pack. I took the harness and attached my stand to it and attached the pack to the back of the stand with the sticks and carried it in that way. Much better. Last hunt I took put the pack back on the harness system and was able to go up the tree with the stand and pack on with no issues. Only thing I had to haul up was my bow.
