Spinning and spincast reels work fine attached to a 5' 6" or 6' light action rod. With some spincast reels I can braid - my best line for the light stuff.
Have a fly rod but hate waving that thing back & forth for every cast. I suppose it necessary for super light flies but I stopped using them years ago.
Yeah.. it's too much work,you can do the same thing with a fly under a float on a spinning rod
I wade fish with a buddy, he fly fishes, while I use a spinning rig to fish. He uses a 9 foot 4 weight, while I use an 11 ft fast action spinning rod, with a cork. We always try to see who can catch more fish. Arguably, he can catch more fish, but not always. I normally dont have to spend as much time fretting with my equipment, as he does.
