Hey guys, do any of you use the Big T Tanglefree 360 swivels on your trolling set-ups? I'm wanting to try them on my double hook spider-rigging set-ups but have not been able to find any. Even Jenko, who makes them, is out of stock. I tried emailing them but got no response. Do any of you use them? If so, do you like them? And where did you purchase them?
