ML Smith,
Very nice HBG. I've got a small pond with them and have talked to a lot of people about them...as far as I can determine you can't tell which Fx generation is which. The famous (infamous) Bubba of Georgia Giant fame was taken from a pond that had been stocked with GG's over twenty years prior.
One of the interesting things about your fish is that it doesn't show any signs of being caught before, that I can see at least. In my small pond, the HBG all have many battle scars from flys that had hooks in them.
