Some pretty awesome info with all of the posts - especially Crappitier with the suspended crappies! I catch most of my panfish on artificials too, Gulp! minnows and Power Niblets being my favorite. When bluegills get really tough, I have found that it is almost impossible for them to resist a tiny live leech - fished with a slip sinker and a 3 foot snell.
Right now we are catching gils on wing dams on the Mississippi River with powerbait or a chunk of crawler. Finding the first stretch of water on the dam out of the current, with the fish on the top and backside mostly. Floating a bobber and small jig over the top has been working well too.
