A friend of mine who actually is a master angler introduced me to Fireline.  I understand that common wisdom suggests that braid is not a good choice for spinning rigs and I have typically used mono.  But on my friend's recommendation I put braid on and found it more resistent to line twist and I find that bird's nests are actaully easier for me to clear with  the braid than with mono.  However I do have a spare spool and I'll be taking either some 10# mono or copoly as a backup.
