This very, very simple pattern has been a fantastic one for me for a few years now. It seems everything eats it including BIG Trout.

Caught some real good Trout on this fly over the weekend in the waters around Mt. Home, AR in fact.

You can simplify it even more by just leaving the cone loose at the eye and not securing it.
