I would say a bream over a pound is big. I fish a private 25 acre pond where 1 pound bream are "common," although I haven't broken the 1 pound mark on the fly rod yet.
Each close to 1 pound on the long rod
12 ounces
1 pound even in my right hand (bluegill). 1 and 2 ounces under in my left (bluegill and shellcracker) (not fly fishing)
Long but not round from a golf course pond
