I think you need to look at the bigger picture. Are there any other species present that you hadn't counted on? Are you happy with all other aspects of the pond/fish?

Longears don't usually attain a very large size and they wouldn't be my first choice for stocking, but, depending upon your goals for the pond, and unless they are thick enough to warrant a total BOW eradication, I probably wouldn't worry too much about a few.

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.
