George,
My experience is certainly not scientific...but I can catch 15 to 20 native bass on my fly rod from a 1 acre pond just about any time I want...and I can not catch a Florida bass from my 3.5 acre pond which is only about 300 yards away. I can actually see the Florida bass; they will often follow me around the shore line hoping I will catch a bluegill they can grab. Its not scientific, but I doubt anyone could convince me that Florida bass bite like natives. I will never have another one.
