Best Fall Time Flies?

[cwoodson]

I have been out fishing the last couple weekends and have been doing decent on the Provo (mainly upper Provo) and middle provo, but i think the fishing should for sure be better than it has been. The only real luck ive had is with streamers and in olive color and to my surprise the nymphs and dries have been dead when usually i do so well on those all year around. I like to fish the Upper Provo, middle Provo, and the Weber mostly and was wondering what is some good colors of streamers for these waters and what type of nymphs should i be chucking? Any advice on fall time flies would be helpful!

Thanks
