Poly, Antron or ?

Polypropylene used as the post on a parachute dry fly will add a lot to
the
floating ability!
The Fly will float even after some fishes caught without cleaning. Of
course, cleaning and drying makes it even better.
I'm a great fan of these parachute flies tied with polypropylene. The use
of
the colour "fuorescent white" makes it visible at dawn, another
advantage...


While checking out the local fly shop for materials to tie parachutes, it
was suggested to use antron. I believe it was suggested because of it's
light reflecting properties (as in more shine.) Any thoughts about this?
