My initial concern would be that SPB would not be as effective in BG management as LMB, but if in your area you regularly see LMB overtake BG, I can understand the consideration for SPB.
I'm not absolutely sure about LMB overtaking BG here. The old landlord pond I mentioned most likely had GSF as any forage fish. Doubt it was ever stocked with BG.
But I think the general consensus is that southern ponds have more of a problem of the LMB over running the forage base as opposed to northern ponds where excess BG can be the problem. Of course that would depend a lot on how much cover the BG had in either case. Someone correct me if this is an incorrect assumption.
