You can't stop them skipping by doing anything apart from changing the broken part, which u can do, have a look on tarty. As for the lockring if you look on it, it says undo on it and has an arrow pointing the way to undo, you can either buy the proper tool or do what i do and stick a nail in the hole and hit it with a mallet or a hammer. But I think the tensile is good enough as I have ridden with both the Tensile and the White industries and when you are riding you can't tell the difference, and if the Eno is skipping and your tensile is fine and working then I wouldn't swap, but it's up to you.
