Chartreuse and krystal flash, have been proven to be a deadly attractant time and time again.
The way the foam is tied allow this pattern to be both a slider and/or a diver depending on how aggressively you retrieve it.
The
foam is tied back over itself to create a air pocket, when this pattern
is made to dive the pocket creates bubbles on the way down.
Keeping
the foam on the top of the fly helps this pattern sit lower than
traditional patterns increasing the amount of hook ups when compared to
other divers and sliders.
