Fishing without a float or weight is one of my favorite, and most productive ways to catch bluegills. But you need to be on your game and focused on your line. Set the hook at the slightest line twitch or even when it just doesn't act "normal", or you will have a lot of deep hooks.

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.
