The PNW Stimulator is the Rockies version's larger, more dramatic cousin -- upsized for the bigger stoneflies that hatch on rivers like the Deschutes and Yakima. Orange and golden stone colors match the salmonflies and golden stoneflies that emerge in biblical numbers during June and July, carpeting the water with protein and turning every trout in the river into a surface-feeding opportunist. You fish it in heavy water with a short leader and the confidence that comes from knowing the fish are eating something exactly this size. Subtlety is for spring creeks. This is stonefly country.
