As I read your post, I had several questions as follows:

1) What is your definition of "watershed"? It seems you use that term to describe your largest pond rather than the more typical use of the term as the acreage that drains into your ponds.

2) What is a "hybrid LMB"? Are you talking about F1's?

3) If your objective is "trophy" LMB, why stock hybrid BG or crappie, or channel cats?

4) Have you considered a system of genetics refreshing for the LMB?

5) What are the genetics you currently have, Florida, native, or crosses?

6) Have you considered shad?

Probably other questions as well, but a quick read resulted in the above.
