Watching videos, I see some tyers start their flies by snapping the tag end of the thread instead of trimming with scissors. Tried it a couple times just to see, met with mixed results (mostly unsuccessful) and realized, most importantly to a cheapskate like me, that I had to leave the tag longer in order to get a decent grip, so I shelved that idea. Anyone use this method?

Also from the videos - what's the deal with a double whip finish? I rarely use anything but a double half-hitch, but if I go to the whip, it's 4 turns and done. If I had to double it up on a whip finish, I'd seriously have to re-think my tying ability.

Scott
