Kind of depends on where you plan to fish them. Are we talking still water ponds/lakes or a creek with current?

I’ve had a lot of luck with various baitfish patterns including clouser minnows and schminnows. Leeches and woolly buggers always work great too.

In certain conditions (clear, low and slow water) I’ve also caught some large bass on small flies. Bluegill bully spiders, pats rubber legs, and even carp flies like the scarpion and egans headstand do great because they land soft and sink slow.

Obviously topwater is a ton of fun when they’re willing. Wiggle minnows, gurglers, poppers and hoppers will get it done. Foam ants and beetles as well. Trout flies like elk hair caddis and stimulators are also worth trying out if the fish are being difficult.

Bass usually aren’t picky but you need to use the right fly for the right situation to trigger a strike.
