Mustad 3399A #12 followed by the #10 and #14. A #12 midge pupae is my favourite pattern lately in stillwaters. No hatch, mayfly hatch, etc., it just works. The naturals are #16-#20.

Not that I think I really need to go smaller but I'm going to start half-tying patterns for fun. This way I can use my #16's to get a sub 20 size.
