Wrighttackle is "wright-on" about Fireline. It is a type of braid called Dyneema. Power-pro, stren, Suffix & other dark green or yellow braids are Spectra,which lose their pigment & get fuzzy with use. Fireline is color fast and does tend to be a little stiffer( feelskind of waxy & waterproof)than spectra,especially in heavier line tests. I have usedCrystal Fireline since it became available on acouple of my bait casting reels with great success. I also use a short 10-15# flourocarbon leader which can be tied in seconds with a double uni-knot. I even spooled a couple of My Stradic 2000 spinning reels with PINK Fireline for my Fishin Chix crews to fish for specks, ladyfish, & bluefish on a poppih' cork with....This stuff lasts much longer than Spectra.
