So I spent all last night tying bivisibles in size 18 with each color cape I have to see what's going on. I figured if nothing else it would be good practice. I do strip all the barbs for about 1/4 of the feather and I tie it in so that the shiny side faces me at a 45 degree angle. If you are familiar with the tightline videos on youtube, my procedure is identical to his for a bivisible.
What brought this about is I just recently purchased the light dunn, medium dunn, and light ginger. I can not, for the life of me, get the new capes to lay perfectly. I tried for over 30 minutes last night and the "U" shape that forms, pushes hackle barbs forward as you turn. It's hard to describe and photograph. I'm not above saying it's probably my technique, as I know that I'm not that great of tyer. I just can't get these to look good.
I appreciate all the advise. I will call Whiting when I'm off work to see what they say.
I apologize for my photographic ability.
