In the winter and early spring the cased caddis is easily one of the most overlooked patterns that you can deploy for trout. The larger one is tied on a #8 hook with a 3.5 countersunk copper tungsten bead. The smaller one is tied on a #12 jig hook with a 3.3 copper tungsten slotted bead.
Aside from tight lining this fly it is great under an indicator as well.
