i dont know of an SBS for it, someone might but here you go..
tye the thread on about a third of the way down on the shank, then bring it half way back up, tye in the wing feather slips facing forwards..
bring the thread to the tail end tye the tail and rib in at the same time to save bulk.. bring the thread to tail end, dub it rib it tye off, then tye in the hackle, wrap it behind the wing then half a turn of hackle infront.. when i say half a turn make sure its underneath the fly and not at the top. you can tye them with hackle in the front but this brings the wing up.. so it depends where you want the wing.. tye off the hackle
add a little dub in the front if its a bit bare.. job done!
very simple
