Re: Montana in July
+1 on what Dean MT is saying; PMD's! #16 & 18 Comparaduns, Thorax style work great on flatter runs, CDC emergers and spinners are very important. Yellow Sally stoneflies in a #12 & 14 will be about (hence Stimulators) and small hoppers will be beginning most likely in the lower elevations. Bring your eastern fly boxs, you will be surprised how often a fly like March Brown or Cahill will work on a western hatch. Oh, leave the 3-weight home and treat yourself to a present...you deserve it for you first trip to the Big Sky. When you get to Missoula buy yourself a #4, either 8 1/2' or 9' (I have both but like the contrast of the 8 1/2' to my 9'/#5)...no sales tax in MT. You will use your #5 most of the time but the #4 is cool for the calm evening spinner fall (we often fish till 11P in the afterglow) after which caddis likely will emerge (tan and dark elk hair style). If you are staying around the metropolis of Missoula you may set up a float trip on the lower Clark Fork and compare the Dinosaur Cafe to the Cajun food you will have in New Orleans while redfishing.
