I did catch one on a drop shot while fishing for RES. I agree with esshup, if you aren't feeding, ( and concentrating them), then finding those few fish might take a good while.

I might try deeper, open water.

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.
