I'm starting to think that a GSF pond with no LMB might be the way to go. Keep plant growth to a minimum, feed pellets, and harvest selectively and aggressively.
I think that's the way to start for a couple of years, after which if you wanted you could add a few LMB for some additional tropheys to the pond. Without weeds present I wouldn't expect much LMB recruitment if any at all. I do know that the NE G & P biologist told the home owners association at the lake I mentioned that they would likley have to restock LMB periodically due to very poor recruitment from GSF predation on the LMB fry.
