Tie in the Pearl Baitfish Emulator Flash at the rear, working the tie-in back a short way with a few locking wraps behind it, then bring the thread to the front.
Figure-8 the Large Dumbbell eyes on near the front with lots of wraps on both sides and underneath, since they take a beating on the rocks.
Palmer the Pearl Baitfish Emulator Flash forward in relaxed turns, gently brushing the fibers rearward as you wrap, and stop a short way behind the eyes.
Line up the tips of two white barred grizzly hackles just short of the flash and tie one flat along each side of the body as ribs.
Take the remaining flash and palmer two or three more turns in front of the feathers to form a bushy head; tie it off.
Pull the head fibers back, build a neat thread collar behind the eyes, and take two or three whip finishes.
