We're big fans of the thorax style mayfly patterns here at PFF. They have a very realistic profile on the water and sit lower in the surface film than a traditional dry fly pattern. The Callibaetis Thorax is our choice for a Callibaetis dun imitation for the lakes and slow moving rivers where they hatch. Don't forget to pick-up some Callibaetis spinner patterns as well.
