Love this fly! I have had great success with the Sheila’s Sculpin on both trout and bass, but it is a great Bull/Dolly fly as well. It has just the right rate of fall for casting to docks for bass. I like to fish it on an intermediate sinking line for bass on the docks, keeping the line just taut enough to feel a fish picking the fly up on the fall, then twitching the fly a couple short strips, then letting it fall again.
