I disagree with you last statement. I use everything that I would use on a large body of water in a farm pond as well. With the exception of deep diving cranks they don't usually work out to well. Just remember to match the hatch. I have had alot of success using carolina rig, drop shot rigs, lipless cranks, tons of them on shakey head, and yes the senko has been a good producer as well.
Actually when C rigging I prefer a 10 inch worm I have caught alot of fish doing that.
