I meant the waddington shanks. It’s a thicke
I may try the chameleon out. Stays straight out eh??For a lot of years I used wire but guys were coming back with flies where the wire was kinked from getting hooked by a fish or bottom ruining the fly from further use. On advice from a couple guides I settled on the same solution as Yooper but use 20lb Chameleon Maxima. Since it is doubled it is plenty strong. When attaching it to the shank I run it all the way through the eye and back a half inch and put good solid wraps on it and it will never come loose.
But, For the benefit of ease of changing hooks and placement of the hook (therefore the solution of having the hook too far back for the safety of the fish) I'd consider suggesting to you to tie that good looking pattern on tubes. It's a good looking fly! Good work.
