i use 6lb. McCoy fluoro 100 in the winter because i can get a 1/32 jig deeper and faster when im fishing structure for crappie. the rest of the time i use the McCoy clear blue in either 4 or 6lb test. I like their co-polymer line because i think its got good abrasion resistance and very little spool memory, i seem to get longer smoother casts with it when swimming 1/16th and 1/8 oz grubs and jigs with very little stretch on the hook set. my knots hold good too. i use either 17lb clear blue or the 20lb super spectre braid on my bait casters. Champ is right the BPS Excel is pretty hard to beat.ive bought a couple reels pre spooled with it and had no complaints at all. im hearing good things about the nanofil i think i'll ck into it this spring. thnx for all the input everyone i think ive learned a couple things especially about what knots to use when tying on a leader.
