This may have been discussed before in this venue but what is the
conventional "take" on using flourocarbon tippet instead of mono? FC
has a 1/2 life of about a gazillion years and when I get a hang up on
the bottom, I wonder what the long term implications are for leaving a
5 foot piece of FC in the stream. Multiply that by the number of
angling days and will there be a problem?

Looking through the catalogs I see a lot of FC and little else. Is that
where the industry is going? Any thoughts on environmental impact? Use?
