6/0 are good. Gamakatsu is what I used last season and they were good. Owner would be a good choice too. I'd get an assortment of lead up to 8 oz. Heavier only helps (except casting if your rod isn't up to it). I haven't had too much trouble with tangling without a 3 way swivel (hopefully you can get some beefy ones if you use them). I just had to use the catfish sinker slides. Not sure if it matters but I figure the slide helps a little so the fish isn't dragging the sinker when it takes the bait. How did they rig the sinker off the 3 way? Seems like any extra line or length from main line to sinker would cause tangles. But, if it works for them it'll work for you. Sometimes a careful cast helps (try to avoid end over end action if you can). Did anyone have luck out there?
