With regards to the fish farms, the first is Andry's Fish Farm in Birdseye Indiana an the other is Jone's Fish Farm out of Cincinnati Ohio. I have heard good things about both places actually.
I am leaning more towards a large bluegill pond myself, but I wouldn't mind catching a nice bass or catfish every now and then. I thought the HSB would add a bit of change to the normal BG/LMB farm ponds that are more often around here.
I can see your point on the GSH, as they are just an extra food source to jump start some LMB growth after the FHM are wiped out (although I will have some pallet structure in hopes that I can keep some around).
