Re: "What do I have to do to catch a fish on a feather fly?"
Maybe it is just me but if I am fishing for crappie it is generally about catching fish. They don't fight worth a turd and I am wanting to fill my limit with as much of that tasty white meat that I can. So, I fish with what the crappie are biting on. Period.
If I am wanting some sporting panfish action, I can catch me some goggle-eye or bluegill on flies and have a field day. Plus on the right gear they will give a crazy wild tussle.
Just my $.02! Gulp away and enjoy the filets.
