An effective jig nymph for prospecting deep runs and riffles, targeting Westslope Cutthroat Trout, Rainbow Trout, and Bull Trout in spring conditions.
Flashback Pheasant Tail Nymph
An excellent general searching nymph for early spring, mimicking various mayfly nymphs that are active year-round and particularly as BWOs begin to emerge, targeting Westslope Cutthroat Trout and Rainbow Trout.
Pine Squirrel Leech (Olive)
Small leech patterns effectively mimic sluggish baitfish and annelids in cold water, enticing strikes from larger, lethargic trout in early spring, including Westslope Cutthroat Trout, Rainbow Trout, and Bull Trout.
Black Woolly Bugger
A versatile streamer that imitates leeches and sculpins active year-round. Slow-stripped through deep holes, it's a high-percentage searching pattern for lethargic spring Rainbow Trout, Cutthroat Trout, and Bull Trout.
