The P.I.T.A. 'March Brown' - I have been tying this 'style' fly, in different patterns, probably since the early 1980s. This particular pattern was a FOTW in the 2nd Q, 2004. It was a topic of a thread back in late 2004 on this very site. An excellent tier, Paul Weamer, ties a similar style called the 'TruForm' and he's probably been tying it since about 2000.
