What does slick really mean? I have a Scientific Anglers AST running line
and a Rio Aqualux clear intermediate running line. When you feel the two
with your fingers, the AST clearly feels slicker, the way teflon feels
slick. But when I cast a wet line, I've found that the Rio gives me
longer casts. I think it has something to do not only with the wetness
but with the fact that my Rio is a little stiffer, tending to lie in
larger coils than the Sci Ang AST line. Practicing your casting is
probably the best and most enjoyable way to get some extra distance rahter
than discarding a perfectly good line in order to have the latest
ultra-slick superline on your reel.
