Size matters more than shade

When big duns are on the water, size matters more than shade. A fish locked onto something substantial will drift past a smaller fly that is otherwise a perfect match, simply because it is not the right mouthful. This is the answer for those days, a genuinely large dun pattern for when the big Kozzie duns pop and fish are looking up for something worth moving for. Fish it on a leader heavy enough to turn it over properly.
