Thanks guys,
A couple of years ago I performed some wet dubbing tests and
photographed the wet twists of dubbing against the original color
(dry). In fact, Hare Tron demonstrated the best color retention, and
many of the ultra fine synthetics performed the worst. Some of my
more course synthetics, like Ligas Ultra Fine and Fly Rite come pretty
close to their package color.

Looks like I have a fun winter project sorting and testing twenty five
years of dubbing purchases (LOL), and dispensing of those that don't
meet my pattern requirements.

I do use natural materials for fly bodies, but like the ability to get
tight durable bodies with synthetics. That's right Tom, you reminded
me of the 8 or so biot colors I purchased a couple of years to
experiment with. Maybe we'll finally get to meet on Penns in
September/October.

Thanks again,
Jeff
