Have the BR members been using them? A-mart and some of the Gamakatsu hooks have this coating, and has a matte grey color. If you look to the Japanese market, quite a few companies are making hooks with this coating. (Nogales, Ryugi, JDM Duo stock treble hooks, and probably a few more that I'm not aware of)
So far my favorite applications for them are trebles and drop shot hooks. Their downfall is you can't bend them back as they'll break.
Let's hear some thoughts.
