One of the beautiful thing about flip-flop and foam bugs for bream is their durability. Trout style dries can be fun to fly but their will be destroyed on a good day bream fishing. I have heard, and believe, that about 80% of what a fish eats lives in the water, not one the water. Leech patterns, rubber legged dragons, wooly buggers, bream killers fished under a foam hopper, frogs, stleath bombers, produce well and doubles area lot of fun. I tye a lot of bream flies on No. 8 Aberdeen hooks, which is about the size of a XL or XXL 14 nymph hook on a softer wire, but I have never had on straighten on me on fish up to 7.5 - 8 lbs. (grass carp & channel cats)
I have caught bluegill on crank baits when bass fishing. Jim Smith is right, bream are the teenage boys of the fish world.
