I think each of us has to find the prolapse device that works for us and our sheep. If you found the spoon-plus-harness, with the harness looser and not rubbing, was working, it might be better to go back to that. Just make sure the spoon is clean. You'll already have given a/bs, when the spoon was first fitted, no doubt - but if it's more than the long-acting one lasts, maybe give her another shot if you fit the spoon again.
