Oh I bet it is. Those fish are probably just tired of seeing wacky worms, jigs, spinnerbaits and flukes.
I'll loan you a flyrod and a couple of these streamers if ya want.
I plopped that Airhead fly down next to a dock at the mouth of a shallow cove, gave it a little jerk, and 7-8 came shooting out from under it, fighting over it. I caught 3 of them before the others figured out it was a snack that bit back. They were all shorts but two docks further into the cove was one that looked 15-16" that shot out, sucked the fly in and blew it right back out before I could set the hook. Have had that happen a bunch. Ya gotta be fast!
