The MOJO Midge is a custom pattern used on the Caney Fork River,TN.
When using a MOJO Midge, you want to dead drift it under a indicator. I suggest 3' - 4' of 6X or 7X fluorocarbon tippet tied to 9' - 10' leader, placing the indicator 2 X the depth of the water. An absolute dead drift is the real secret - you want the MOJO Mide to appear to the trout as if it is not connected to anything. Using this method to fish shallow water has put some big fish on my line. Also, when the trout begin their surface activity in the form of dimpling you could be in some of the best midging of the hatch.
If you want to construct a deep nymphing rig for water over 4' deep tie a #16 Humpback Scud onto 3 feet of 6X tippet connected to 10' - 12' of leader then add 2 - 2 and a half feet of 7X tippet to the bend of the Hunpback Scud hook. The second fly should be a midge - a MOJO Midge midge is a excellent choice again set your indicator 2 x the depth of the water.
