Whats a good setup rig for river fishing?

What type of rig would you recommend for river fishing for catfish,trout etc.?Right now I have a lot of bank sinkers and barrel swivels.What kind of line would you recommend 30lb braid? 30lb mono? What else should I add to my equipment?

Thank you.

If you fish for catfish put on some weights get a treble hook put on stink bait get a stick put it in the ground get 30 pound mono.
For smallmouth take a creek chub put a small splitshot and cast it out and let it swim around.
