What about Oliver Kites Imperial. Tied as a Large Dark Olive pattern it incorporated heron herl for the abdomen.

Peter Hayes' PhD is without doubt my favourite olive imitation. Muskrat provides the grey in this pattern; also in common with another successful grey bodied fly it has an underbody of yellow thread.
