I use Wicked Sticky stinkbait or big crawlers for the Channels and your best bet for Yellows is either live bait like creek chubs, frogs, toads, bullheads, bluegill ect. or cutbait. Use a pretty good size hook and big bait for them big Yellows, your best bet on Yellows is putting out a bunch of throw lines, you can have 15 hooks in the water so you can cover a lot of ground with 15 lines with one hook a line.
