Vulnerable Dun

I have been tying a few Vulnerable Duns (a Chris Watson creation) in preparation for the new season. The fly has been tied on various sizes from 14 down to 22 using Aero Dry Wing with a few strands of Krystal Flash UV Pearl for the wing, a body dubbed with Superfine and ribbed with thread (ropped and coloured with permanant marker), a shuck of white McFlylon with a few strands of Krystal Flash UV Pearl and a hackle, in this instance, from a Metz Grizzly Hackle.
