snipped good stuff

les, good to hear from you. Hope all is well! You've clearly given this
fiber thing a deeper look than my generalized natural v. synthetic. You
bring up one great point regarding floating flies insofar as some dubbings
are impregnated with water resistant chemicals. Such dubbings untreated
would avoid the usual wetting effects, so long as no "floatants" were
applied.
With the exception of the use of antron or other trilobals
for bubble retention, I have yet to find a synthetic dubbing I liked for
subsurface, and I always mix the trilobals in with some natural fur.
