This fly was a collaborative project for between Texas guide Daniel Hughes and myself for the Devil's River in west Texas. Our goal was an all around fly that would catch, everything....in this case everything included carp, smallmouth, sunfish and gar. Since its inception, the leech has proven its worth and accounted for all these species in a number central Texas rivers and lakes. In particular this fly has done very well on carp. However, more recently I caught several smelt on the California coast on this fly. In New Mexico this fly accounted for my personal best catfish. While olive was the original and most productive color, purple and black has been proving itself more and more on the water.
