I am worried about an apparent lack of skill or confidence when tying-finishing off a fly from 14 and smaller.
When I'm done with the hackle I rather use a half hitch to hold the hackle wrapped, and then do the whip finish. I've never had troubles with the hackle unwrapping. So I've developed the need to use the HH before the WF.
I do the WF knot by hand 'cause I find it faster to achieve.
How many of you guys do the same or something similar?
