Yeah, I try to not make it too complicated.
For a sucker or bullhead in the 8″ range I use the Team Catfish 8/0 Super J hooks. If Gama’s I’ll go with their 10/0. The two are the same size although the TC is heavier wire.
About 18 inches of 80 pound Nuclear Yellow line, never more then 18″. I make sure the swivels are a min of 90 pound test with a 4 oz sinker. In spring there might be a need for more weight but a person can get by with less most of the year. Since it’s a slip sinker it really doesn’t matter what size it is as long as it holds the bait where you want it.
Then 80 pound Team Catfish Tug O War braid for the rest of the line.
I don’t use lighter line for the leader as the cat will tell you what your weakest link is. But many fold do, some don’t use any leader at all.
The hook gets down sized as the bait size is dropped.
Good Luck!
