Oh, dont get me wrong CC. I am sure they would catch fish. I do understand the concept. Its the same as when you use a flasher above your trolling spoon for Salmon. That big blade/weight above that tiny jig is the same concept. Its just as a jig maker myself, I think I could have designed that better. I use those snaps they use for my jigs and know how small they are, therefore, I can only imagine how small that chain is. I wouldent trust it.
When I want to get the fishes attn.....I use a bigger spoon/jig. once they come in, thats when color counts, than, jigging presentation and than lastly whats on the hook. You would be amazed on how big a spoon/jig a perch, bluegill will suck in.
Another thing I dont like is, I see SERIOUS line twist jigging them. They should put a swivel on top. So again, I understand the concept and yes, its not a bad idea, just bad design. IMHO
