[VFB] Replacing fly lines

[Tom Davenport]

How often and under what circumstances do you guys throw away and 
replace your lines?  What indicators or performance problems do you 
encounter that makes you decide that it is time for a particular line 
to go?

How long can you expect  a seldom used line stored on an extra spool to 
last?

I've noticed that some of my older lines have tiny cracks in the line 
coatings, but they still cast just fine.  I have noticed that floating 
lines with this condition don't float as well.

What are your observations?  Inquiring minds want to know.
