Hey guys & gals - a fly pattern I am tying requires very sparse hackle down the body. It is a bug made of caribou hair that is very closely trimmed ( much smaller than traditional bugs) however I need very sparse hackle going full length of the body. I have tried striping one side of the hackle off but to me that?s a waste of good hackle.

The hackle needs to be very sparse as it is fished as a traditional salmon fly (just beneath the surface).

Anyone got any suggestions?
