Clay, (and I apologize for this thread getting hijacked!), are you trying to target Bigmouth Buffalo, Smallmouth Buffalo, or both?
I've caught both on flies, but not many of either. There's a guy I follow on Instagram that seems to catch Smallmouth Buffalo with regularity on flies. His fly pattern of choice is something like the following:
Beadchain eyes to get the hook point to ride up, a brown-ish Woolly Bugger body (shorter than normal hackle), and a tan ultra chenille tail. Or, basically something like John (Bartlett) Montana's Hybrid carp fly, except the color of the tail. Also, the length of the tail appeared to be longer than you'd normally do for a Hybrid.
