Byron -

No, I rarely time anything I do these days, except my morning times and distance on the treadmill, both of which are done automatically as soon as I turn the treadmill on!

However, since I sometimes have difficulty in pairing two separate bunches of hackle fibers - brown and grizzly mixed for the Adams tail in this example - I've found that it is more efficient for me if I glue these two feathers together ahead of time, and sometimes I might glue several or more together at the same time - and I probably get a half dozen, or maybe a few more, flies from each glued pair.

Since I glue two matching feathers together that have the same barbule length, I automatically get mixed colors of the same length, and approximately the same quantity of each color, with a single pinch.
