FireLine=Superline! The term "SuperLine" was introduced in 1996 - and it has remained the world's true SuperLine ever since! It is simply the strongest, most abrasion-resistant superline in its class! Not a conventional braid and not a mono - Thermally Fused FireLine changed the fishing line landscape forever.
Tuff line but for spinning reels, it delivers a cast poorly.
I've used a lot of braid but this was a mistake. Very tuff and would be good for a boat rod / bottom fishing / trolling....
but as far as use on spinning reels, it sucks. It's very stiff, comes off the spool poorly and I can only get about a third of the casting distance I get on most every other braid I've used. This was a mistake for my spinning reels.!
Tried spider wire fluoro and braid because that's what I used 20 yrs ago and it has turned into garbage over the years. Fireline is great for my style of fishing. Can't go wrong with Berkley, Nano, Fireline, Trilene even their rods are good.
