I'm a big fan of carp fishing. I use different carp fishing methods and yesterday I decided to try a waggler float fishing for .....bluegill! And those guys were nailing it like crazy. I started with my hook on the bottom of the river but bluegills didn't event touch it. Then I readjusted the split shot pattern the way that would allow the bait to sink slowly, so called "fishing on the drop". That made a huge difference. Who would've thought! The bait was: quick greets+creamed corn+white bread+paprika. I just rolled it into small dough balls and put it on the hook #10 with the point exposed. It seems to be too much for bluegill but the ponds and the river banks I have access to are heavily pressured. The tackle has to be a little sophisticated if you wanna catch something.

Wagglers, stick floats, homemade hybrids, casting bubbles, and fly fishing strike indicators are all I've ever used when targeting Bluegill. 

I'm a snob when it comes to fishing with floats   

It's also fun and easy to make some extremely sensitive floats out of balsa wood, quill, cork, etc.
