I'm tying up a box of flies for my Dad's 80th birthday which is early next month. He doesn't fish dries so I am tying wets and nymphs. I'm not that familiar with east coast hatches. I know he likes light and dark Hendricksons. I also have tied PT with and without flashback, Prince, Biot nymph, BWO nymph, Copper John, soft hackles, Diving Caddis, and Graphic Caddis.

Any suggestions? Please include size and color.
