On a related note, my all time favorite bait for spawning BG? A #8, chartreuse "Miss Prissy", by Accardo. I trim the rubber legs back to about .5", and tip the hook with a couple of Beemoths.
The added weight lets me cast it further, (no flyrod, just ultralight), it rides lower in the water, and it provides a "taste" for the light biters.

It is killer.


"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.
