That's what I get for getting a snack before logging into PondBoss... This thread gave me such a start that I've got pistachios everywhere.

I will only say that I believe the photos posted by Yolk and Jwwann show the absolute polar ends of the spectrum where GG, and HBG in general, are concerned.

I've had HBG for years, and I've seen neither of those extreme examples.

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
