Keep it Simple and Swing them up
The best things are life are often simple, and the same goes for flies for trout. You cant get much more simple than orange thread and a partridge hackle. The hackle imparts the life, the breath into the fly, giving it the buggy difference in the water. The orange throws out a flag to trout that says "I'm orange, eat me". Perfect for swinging in rivers or on a slow draw or static retrieve in lakes, this fly just calls for water and fish, the rest is up to you.
