Good Dry flies for Uintas?

[Chigimonky]

Hello all, I am heading up for a backpacking trip in the Uintas very soon and could really use some advice on what dries will work up there. I was there last week at around Washington lake using black gnats, humpys and adams and I did have a great time catching some brooks and tigers but there was much of the time when fish were surfacing all around my flies and left them alone. Any advice on what flies are hot in the high uintas and in what size so I can stock up before the trip would be much appreciated!
