I've run the revolvers since back before they were Teraflex. I have over ten years on them now. The do feel a little different, but they work. I also removed the track bars and sway bars and get good flex. (Just because I did it doesn't mean you should, I'm stating what I've done not something to copy. This is not a warranty, and I'm not liable for what you do with your YJ.)
After ten+ years, they are looking worn and I will replace them at some point but they still function. They need to be lubricated, so get a grease gun.
In addition to opening up, and letting the wheel drop more, the also allow rotation. This is why I think they feel different when driving. Without sway and track bars, the axle is not located under the vehicle in the same way. Makes for interesting pictures.
Since there is a lot more drop than compression, it took me a while to figure out a shock setup that worked well with the revolvers.
