No, the GSF are just a novelty fish for me. I have LMB for the top predator. If I have the same outcome as Dave Davidson with GSF he puts in his pond, the LMB will eventually wipe out my small number of GSF.
Nearly every pond around here has GSF in it unless it has been stocked specifically to try and exclude them. Fish in the creeks and 95% or more of the sunfish caught will be GSF. In a pond without LMB they will over populate and stunt. At least that is the way it was 30 years ago when taking my small kids fishing in a pond with only GSF (that I know of). Could not bait the hooks quick enough as was fish on instantly when it hit the water and biggest GSF was maybe 4".
So in my opinion, a GSF only pond is going to end up with lots of small, stunted GSF over time. I would guess the original stockers would get big but when they die off from old age the pond would be full of small GSF. Basically the same trajectory as a BG only pond but maybe taking a little longer since the GSF do not spawn as often and the larger mouths would eliminate more of the offspring. My un-expert and WAG opinion only.
