I currently own an XOP Air Raid Evolution and 4 XOP sticks. They weren't bad, but not nearly as light as I was expecting them to be. I was thinking in the 20ish pound range, but the whole set up with synch straps and everything is somewhere around 30 lbs, maybe a bit more. And I'm sure it's me, but I do not like trying to hang that sucker, I swear like crazy trying to get it in a tree. For those of you debating on single or double sided steps, go with double lol the single sided steps were a pain for me. I personally will be selling it soon and getting some sort of climber.
However, that's not to say it's not a good stand. If you're on a budget and looking for a light(er) weight lock on, the XOP has a lot going for it, just not for me and my outta shapeness lol
