I would be skeptical of removing the largest BG in your pond if your goal is give your LMB every chance you can. I think it will create a gap in your food chain.
How many BG do you plan on removing? How large are those BG? How large are your LMB?
No more than 20-25; enough to have a good mess of fillets. Currently, we've got bluegill of all sizes because we gave them nearly a year head start before adding predators.
In October, largemouth bass would be approaching a year old.
