I'd go traditional in a five acre pond with high quality stockers, lots of forage and good harvest practices.

Then I'd go with a one acre pond, all female largemouth, fatheads, and intensive feeding.
The dumb fatheads will feed on pellets all day, and the female largemouth will gorge themselves on fatheads until they practically explode. Run the feeders right over the top of well placed structure.

There are plenty of ways to do this, but that would be my favorite possibility for ultimate potential size.

Holding a redear sunfish is like running with scissors.
