To many varialables to narrow down how to rig up.... lakes? rivers? ponds? Rocks? Timber? Flatheads? Missippippi whites? channel cats? Blues? What kind of bait??

It all makes a difference. Channel cats feed mostly right along the bottom. Mississippi whites and flatheads feed a bit up off the bottom. I primariely rig my rods 2 ways. Either with a egg sinker, swivel, leader, and hook. Or I go with a 3 way swivel... and use 2 leaders, one with a hook and one with a weight. Size of the hook should be determined by the bait your fishing with. I'm sure others on here and more qualfied than me about this so I'll let them have at it.
