Connor, I recently caught a huge GSF mix from my pond. It had the GSF markings but not the elongated body. No idea what the % was on the mix. I neither weighed nor measured it but it was 9.5 to 10 inches. Biggest one I've ever caught.
It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
Without a sense of urgency, Nothing ever gets done.
Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP
