Has anyone tried managing for big GSF? Is there anything more to do than releasing the big ones? Is that even the right thing to do? I put 25 GSF in my pond last year, and so far, I'm quite pleased with them. They have grown a lot (about as heavy as my 9" BG), and they will hit when nothing else will. I think I've caught at least once all that the otters didn't get. They hit on whatever I fish with: flies, spinners, twister tails, and poppers.
