Ken that's perfect. I look at forum advice the same way I do as buying offshore import machine tools.... if you're willing to tweak on it, maybe break it down into individual components and Polish it up, then it makes a pretty good foundation to build upon.

It depends. It always depends. Temper the advice with your own, unique set of variables.

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.
