I have. They really catch. But the only problem is the very small eye. I made the mistake of using clasp brass barrel swivels. I lost a lot of big ones, as the clasp was pulled open & hook was gone. I think the biggest we caught was a 36# Blue. So it might be best to use a double barrel brass or SS swivel (without a clasp), and use a good mono strip to connect to hook. 50# test might be advised. That 36# was really great. The jug would vanish, then fire out of the water like a cannon in another spot. The Blue would regain strength for a few seconds then take it down again. I am thinking we chased that one for 2.5 to 5 minutes, as we just kept missing grabbing the jug before it dove once again.
