TK, I purchased some Pierce Hooks from Cabelas last year, an english company, I think. They have a black nickel finish, a shorter shank than gammys, and are sharp out of the box. I use them on certain plugs and spinners, for the same stealthy reasons you do. I think I ordered them from their tackle catalogue. If you are interested, and can't find the catalogue, give a holler on this post, and I will dig out my catalogue,and give you the order #s JCB, Mortac advertises in every STS I hve read recently, should be able to get their site info in that magazine.
