It's simple cause I avoid perpared baits all together. Most of them stink and are messy. I normally use bait that is free for the collecting or cheap. Here is my bait list.
1. Catalpa worms
2. Earth worms
3. Turkey liver
4. Chicken guts (intestines) are great but are nasty!
5. live Bream (perfer green sunfish when targeting Flatheads but will use whatever I can catch.)
