The bullet bunny sculpin is an excellent streamer, imitating every trouts favorite meal, the sculpin. You can fish it multiple ways. Dead drift or stripping it through the water close to the bottom. I like to tie a dropper to the hook. One of my favorite setups is Hoots River Juan as the attractor fly followed by Bullet Bunny Sculpin. Yes a small fly being chased by bigger fly actually turns on trout. 4X through 6X tapered leader and tippet are good choices depending on size.
