We are stocking some new fly patterns from Idylwilde that have been working great.
Both the Loop-wing Dun and Tilt-wing Dun in Blue-winged olive (BWO) size 18 have been hot...both in Montana and Wisconsin streams.
For nymphs, try the Mini Jewel Crawler in 16 or 18, or Morrish's Biotic Nymph, size 16 olive or black. Trout really seem to like 'em.
