This pattern is an orignal pattern developed by Cory Cuje of Old Dominion Trout Bum. He developed it to be a fast sinking mayfly imitation that still had a lot of movement. The drab body keeps it looking like a true natural in the drift, but the little bit of flash in the collar that it features, keeps fish looking for it.
