Never fly fished for blue gills, but unless they've grown since I fished for them it seemed an u/l spinning rod was almost an unfair advantage. I think of 6 wt rod as something I'd use for salmon or large rainbows.
Then again, I've shot spruce hens with a .480
About the most fun you can have flyfishing for bluegills is to use a cork popper and watch them blast it on the surface. Just my luck and maybe it's just me, but it seems that every time I hit a lake to fish for bluegills from shore, it happens to be windy. Casting popping bugs or large wooly-looking flies with a two or three weight rod into the wind kinda sucks.
In this case, it's not about whether the rod will handle the fish, it's about whether the rod and fly line will handle the fly....
