I have three sets, all assaults. Best thing since sliced bread, IMO. I only go to about 12-14 feet, and three sticks are adequate for that. Shot angle gets mighty acute beyond that.
Very often, on public land I hunt, where it's legal, and it's not everywhere, I'll leave the stand (chained and locked) and uppermost stick in the tree and pack in only two sticks, which are very easy and quick to position from the ground. It's a deterrent to theft. Of course, if somebody really wants the stand and/or stick, they'll be able to get it, but it hasn't happened yet. Then again, most of my stands are a mile or more from roads, and most slobs don't want to work that hard to steal them.
