The one I got has thicker rope, but I think that works for Lacey since she doesn't want or like a huge release. It releases just enough to not just crank on her nose, but it's definitely "tight." I've never had a problem with it being overly tight though. It's usually about as tight as a bit would be, ie continual "it's there" pressure but no "what is she trying to tell me" pressure all the time. Also, I ride Lacey with basically no contact at all in it, if I want to ride with contact I use a halter, so that may have something to do with our differing results.
I'd think that the metal rings would help it release more, my one concern is that if it releases a lot, could it start sliding around on his face? Maybe not, but I thought I'd mention that. :)
