Rod sensitivity, line, and the amount of weight used plays a crucial role in both jig fishing and bait fishing on the rivers. I like a 6'0-7'0 ft rod w a fast tip and some backbone to set the hook. Water depth and speed of flow are also things to consider. The heaviest jig that I'll fish is 3/32 oz, often tossing 1/16 oz. All colors work just as long as it's black!

With bait, use the least amount of shot you can get away with to keep your presentation down and naturally flowing downstream. If you're snagging, you're using too much. Maintain contact with your lead as you drift your bait, too. Small lifts to tick the bottom will help to avoid snags and also help you feel the takes.
Hope this helps!
