I picked up a few packs of these because they looked similar to my favorite now-discontinued bass hook, the C52S-BLN. The hooks did turn out to be pretty similar, the finish on these is more of a dark gunmetal gray than the deep black on the C52S, but that's not a big deal. My only real complaint is that they're about one eye length shorter, but that still makes them all but identical to the Gamakatsu B10S, but at a more attractive price point. All and all, a very good hook for my intended uses.
