Been fishing subsurface flies for gills with an 8' 4wt that I built. If I didn't see them take the fly I would have no idea that they did. Very light bites. Not alot of experience with bluegill and a fly rod, up until now it has been all smallie fishing for me and you know when a smallie hits. When you fish for bluegills are you waiting for the tick of a bite or are you watching for any movements on the end of your fly line? Maybe I shoud try a lighter rod?
