When creating a wing post for Klinks or Paras I always use Tiemco Aero Dry Wing, having found it covers all my needs in
a wing post material. When you start to unwind it from the card,
you will find that it naturally splits into four strands, I find one of these strands doubled enough to form a post, then I don’t like bulky wings. I form the post by running the silk down to the point where I want the wing to be, I then take the piece of Aero Wing under the shank half way and pull both ends upwards, a couple of figure of eight turns then whip up the post for a couple mms, place the hackle against the post in position and whip back down, tying off the rest of the stalk as I go towards the back of the fly. I then complete the rest of the fly before winding the hackle and whip finishing to complete.
The choice of wing/post colour is one of personal choice, one guide I know swears by pink and says orange puts the fish off, other people use orange and seem quite happy with their catches, myself, I use med grey and find I can see it better than any other colour, in fact it seems to catch the light and almost glows.
