I've got mostly all my fish on buggers. Just experiment with colors and weights. I tried my favorite spot last week and couldn't even buy a hit. It was really good late nov and early dec, but hasn't been too great lately with the low water. Its great in the spring, and pretty consisten throughout the summer. My best pattern has been a crystal bugger, lead eyed, beadheaded, or conehead. I was fishing a size sixteen mini bugger one day and was killing the whities, but for the walleye, largemouth and occasional sucker, carp, and catfish, go with biggers ones. Size 8-10 are my favorite. Just make sure you have enough weight to get it down to the fish. I think a lot of the time i'm not getting fish is because the current swings my fly up near the surface. Trial and error til you get it right ...
