I caught over 100 crappies, 2 small bass, 1 bluegill, and 7 green sunfish. The crappies probably averaged around 9". I measured one at 10", and another at 11", but didn't bother measuring any others.
I tried a variety of patterns, and the two top producers again were the microjig, and small Kraft Fur Clousers with beadchain eyes. White/red worked very well, but I can't really say I tried a color that DIDN'T work well. I caught a bunch on olive, too, as well as pink-n-white, and also chartreuse.
I think this one was the one I measured at 11"
