I have used a hackle guard that is 5 holes on a tin 'bar'. After securing the hackle (held in fingers) with a couple of firm wraps I apply the hackle guard for about 4 more wraps. That usually keeps fibres out of the way. Then I can put down the hackle guard and whip finish.
However for a few years I have been wrapping hackle this way . If you seesaw the thread as you wrap forward (maybe a little slowly), no hackle is trapped and once at the eye all you have to do is whip finish. At that point there is nothing to bind down or cover up. I have converted a few others in our club to the same method.
