The Crooked is good, This is the time of year BWO hatches ramp up and can hatch side by side with the PMD’s. Be ready for both. We have a Cut Wing Extended Body PMD that the fish seem to eat when it’s an overlapping situation just great. And the Furminsky’s BWO is also one you can’t be w/o on the Crooked for the next 2+ months.
Of course nymph action is awesome, I like a one fly rig on a euro leader or with a NZ wool indicator and the one fly is mostly to minimize the cleaning of moss of the fly and get it done quick for another drift.
If you fish 2 flies, great. No worries.
