Hook: B160 #12
Underbody: peacock glister
Body: Foam cylinder
Post: 2 - 8 strands of polypropylene
I tied a few of these today. I carry them in both my river and stillwater boxes as a general beetle. They also double up as a good dry pattern for the Duo, hence the oversized posts on some.
The shortshank B160 #12 has a shank equivalent to a 14 so by tying them big you can trim both the body and the post down to give a few sizes. The trimmed down version bottom left came out of the box having caught some fussy fish last season.
