Sounds good, Marc. Obviously, you'll know a lot more once the ice goes off and things warm.
If the bluegills are primarily of that smaller size (i.e., <6 in), don't jump to the conclusion that your largemouth bass are crowded. It's possible that the pond community is relatively young, and was not stocked too long ago. Any possibility of that?
Sounds to me like you already have a good handle on how to assess your new fish community.
