Barrel swivel with main line through it then bead tied to another barrel swivel. off this swivel tie a leader 6" long to a pyramid sinker. of the free sliding swivel tie a 6" leader to a hook. put a split shot above the free sliding swivel to keep it from backing up the line!
By the way, I once had a Siberian Husky named Yukon Jack. He was the best dog I've owned.
I just read an article about this problem and they fixed it with a drinking straw. They ran the leader from the swivel through a drinking straw cut to fit the length of line where it tied off to the weight. This kept it from tangling with the line during casts and drifts. Good luck and let me know if it works. I'll probably be trying it when the weather warms up.
my humble opinion..thats way too much stuff for channel catfishing. just hook line and sinker is all you need. split shots make ur line easier to break which defeats the purpose of having a leader. the amount of channels you catch that are capable of breaking anything over ten pound test is few and far between.
When I fish for channel cat in very fast water i use barrel swivel then a split shot spaced about a foot ....... a heavy sliding sinker .......nother 8 inches split shot then about 4 or 5 inches then the tubular sticky stink bait worm with treble hook retied to my 30 lb braid.
