Glad to hear that, Benny. I will have to try some trimming on the few I've tied. Mine were my own attempts though, based on his idea, not his fly.
As for the tag dropper, I've been using the triple surgeons knot and the top tag method. I do not believe I've had that fail due to knot failure. I've caught a couple big trout with this system too. Trout to 23 inches anyway, both by myself and by others on nymph leaders that I tied for them.
This 23 inch, 5.5 lb trout was caught on a rig that I tied for a buddy:
And this 19 incher, 20 incher & 15 incher:
YMMV. Make of it what you will.
