If I were limited to only one fly to fish the San Juan, this would be it (sz 22 during Spring and summer and sz 24 during Fall & Winter). This midge pattern utilizes the tying techniques of the Tav's Big Mac and is offered with a shorter shank hook in the smaller sizes found most of the year on the San Juan and other tailwaters. The segmentation provides the aooearance of a natural midge pupa and it may not take long for this pattern to become a regular in your fly box.
