It took me months of failed attempts gotta be part ninja I swear especially in the shallow clear creeks I fish. My buddy goes out and hammers them almost every cast he makes towards one. He told me, gotta be a ninja, get in front of them and wiggle the fly they have terrible eye sight, hold on. I started getting better luck when I moved to bright flashy flys. The one this guy took and several others since then have been a white wooly bugger with a gold head and chrome tinsle like wrap around the body. They can't resist it.
