Seriously, buy a Claw, take the lockring off it when you buy it, and clean all grease off with thinners etc, and loctite it. I done it to mine, about 18 months ago, not touched it since, It has never ever skipped or casued any trouble what so ever, I gonna stick my neck out and say that it skips less than a hope/king, lasts just as long, and only costs a tenner, has as many engagements as I ever want, and is disposable
