Amother idea I've seen in the midwest is tying a dahlberg diver on an inverted hook.
Hook point up. Then taking some rubber cement or goop working it into the deer hair collar to act as a weedguard around the hook point. Those things work real well in the slop on MN lakes.
If you want I can get some more info on the fly. Chris Hanson a FF guide for warmwater specises in MN came up with them. He has a tying video as well that shows his patterns. But its a pretty simple design a deer hair diver on an upsidedown hook with a toughened up collar.
Hope this helps
