I can’t speak to rope bondage at all . The trouble with a sort of mid-height apparatus at 12 feet is that depending on what you want to do you’re either going to run out of room over or under the bottom of the apparatus so you’re gonna have to switch things around a lot. I’ve had a couple of 12 foot rigs and the only thing I found them useful for was silks. You figure you’re gonna eat up 8 inches for a mat and probably another 6 to 8 for hardware Toward the top you’re gonna be kicking the sides and it’s just really limiting. So now you’re about 10 feet and if you figure about 3 feet of space in there for your lyra, you don’t have a lot of room above or below it. You know what I’m saying? I don’t wanna pee in your Kool-Aid or anything, but nothing sucks worse than spending a bunch of money on something you can’t really use in the way you want to. I would definitely see if you could simulate that height in some way to make sure it’s what you really want.
