Nice concept but a big issue for me: If you use a stout continental type #4 hook like I do for large river fish, the inside diameter, even on the Extra Large, is too narrow to slide over the hook point. I do just as well by cutting off the end of anti-tangle sleeves (which I shorten anyway) and also save $$. However, they do work well as intended on a standard hook.

I’ve used this on a lot of rigs since I’ve got it and caught plenty of nice Carp. Holds up pretty good. I like that it’s re usable too. I’ve had maybe one or two rip.
