garfish, Tube lures are simply a piece of 3/8 diameter surgical rubber tubing normally floresent green with a sinker at one end and treble hooks out the center and other end, all connected by a piece of wire. You cast and retreive it a fast as you can or troll at about 8mph. They are heavy thus the heavier tackle. I'd suggest 6 to 9" 60lb leaders. Check Cabella's or Bass Pro --try
