I've got an old black stand my brother got and I use it when i want to go in and out real quick. The thing only weighs probably 10-15 pounds.. the lightest I have ever felt. But MANNNN its a bit scary. I wear the harness in that thing and make sure I'm very careful. Almost on adaily basis, that thing rocks side to side while I stand or shift my weight in it. I have come to get used to it. Like you said, on mine its the teeth as well. But its spooky sometimes. I have another that I use primarily, but its too heavy to lug in and out on a daily basis.
