Figured I'd tie this in tandem with the GD Wulff and have a real para Drakes; first time with one of these so there's bugs to be worked out
hook - Mustad 94840 #10
thread - Danville Flymaster Plus yellow
tail - moose body
body/head - elk hair olive
wing - Congo Hair grey
hackle - grizzly dyed bright green
rib - tying thread
Part 1
mash barb and attach thread at head (gap width)
cut a clump of elk hair (be generous, you'll want more than you think is necessary); clean, stack and measure for length (shank x 1.5)
trim the butts, a couple soft loops right at the hook eye and then pull firmly, letting the hair spin around the shank
trim butts
flip fly over and tie a hank of Congo Hair (or any other hydrophobic fiber you care to use) on underside of hook
flip fly back over, post wing with thread wraps and apply a bit of Sally
tie in hackle up to top of post, shiny side out (I have 2 hackles here; hedging my bets in case one is not dense enough)
cut a clump of moose body hair, clean, stack measure for length (shank x 2)
tie in, trim butts and cover with thread wraps to smooth out underbody; return thread to front of wing
