Thanks to Mark Kraniger for developing this pattern.
Kraniger's two tone nymph
Hook: Tiemco 2302 or Daiichi 1560 #10-12
Bead: black, 1/8 or 7/64th
Tail: Pheasant tail fibers
Body: Fine & Dry dubbing, color: hare's ear
shell back: pheasant tail fibers from the tail
Rib: fine red wire
Thorax: Brown squirrel dubbing spun in dubbing loop and pulled back like a soft hackle.
I fish this under an indicator, trolling, or cast/retrieve on full intermediate sink or clear tip lines. Great searching pattern. Another fly that caught a pile of fish in the Basin last fall.
