Everything is set for our July 4th float trip somewhwere near West Yellowstone. (Possibly the Madison, Henry's Fork or somewhere else at the guides discretion depending upon fishing conditions.)

Wonder what types of flies I should get busy tying in the next couple of weeks. I would welcome any suggestions as to patterns, sizes, etc. Should I be prepared with adult dries, emergers and nymphs, streamers, etc?

I have to admit I am not an experienced tyer but have done some. I'm used to fishing dries in the #14-#22 size range and nymphs even smaller than that. I did tie up a few Yellow Stoneflies the other day and that #8 dry fly sort of scared me.

Any advice will be greatly appreciated. Thanks.
