Okay this may sound kinda dumb, but here goes....

How do you fish emergers? I've always assumed that they were meant to be fished in the film on a dead drift, but lately with winter time thinking going on, I'm wondering if maybe I should be using them subsurface on a swing, or dead drifted as well. If you goop them to keep them up, do you goop the whole think or just the fluff?
