Then roll cast to another spot and start teasing all over again. When I was a kid, my rule for keepers was that they had to be big enough so my fingers would be an inch apart when I held around 'em. Now, I want to see two inches between my finger tips to start thinking of panfish fillets back home. I'm talking about a Bluegill the size of a 45 rpm record. Think about it.
Spring is definitely the time to catch bigger fish, shallower.
Once in a while, they stop jumping surface patterns. This is the time to switch to underwater and the Cape Cod fly. You'll have a hard time keeping it away from the Perch, Pickeral and the Bass too. The way to target the Bluegills is to cast away from cover to more open water. Sunfish avoid the hunters hiding in cover so casting to clean bottom or further from shore will catch you more sunnies and fewer of those undesirable Largemouths and waterwolves.
