Lake Gaston was exclusively a LMB lake until a few years ago. No one knows how the spots got introduced into the lake, at least no one that is talking about it. In my opinion they are much more aggressive than the largemouths. It is hard to catch largemouths now in the deeper portions of the lake where the spots seem to be prevalent. Even though they are generally smaller, I love fishing for them. We are starting to catch some in the 3 1/2 - 4 pound range now.
