I agre Hap. Many years ago, when most all of us used necks (which weren't the best), I used to take the feathers off and put them in zip lock bags with the size noted. Not sure it really saved a great deal of time................

The other thing is this. If speed is that important, you have to count your preparation time as well. Not sure, in the end, if a great deal of time is saved.

I think Hap's explanation of tying in rhythm with the same number of wraps, etc., etc. is the best way to speed up the tying process.

A simple habit like keeping your scissors in hand the whole time saves time. Reaching for tools wastes time.

I took an all-day tying class from Jack Dennis many years ago. He is famous for tying deer hair patterns. He had an entire deer skin draped over his lap while he tied and could then select the most appropriate hair from the skin for differing patterns. Sort of extreme, but that is what he did. Scissors never left his hand either.
