Thanks for the help:
My researches produce the following recommendations, generally for the Rocky Mountains and some specifically for Montana in Late summer, if I have not made errrors in collecting my data.
Especially, Parachute Adams, Elkhair Caddis (or Caddis generally?),
Also: Blue Wing Olive, Pale Morning Dun, Madam X
with TERRESTRIALS: Hopper, Cricket etc.
Hare's Ear Natural Pheasant Tail (not sure on the title of that one)
Prince, Hare's Ear Flashbacks and Scud (Not sure what color is proper)
Black Stone, Brown Stone,
Hare's Ear Beadhead, Pheasant Tail Beadhead,
Peacock, Copper John, (K) Stone Brown (What is "K"?)
Black Rubber (Don't know what that is)
and STREAMERS as follows:
Crawdad (for general purposes, I added this)
Rainbow Trout Epoxy, Silver Darter Epoxy,
[and I am unsure about the recommendations for several I recognize as
"tradition" streamers such as Grey Ghost, Ghost Black, Mickey Finn,
Hornberg ...] Do I really need these?
I have to either tie all of these or buy them, and to buy all would be too expensive. I am confident of being able to tie at least half of them, the only exception being the small emergers & nymphs etc.
Any advice about your personal preferences, such as eliminating some of these, or adding others, would be much appreciated.
