There are lots of original FireLine fans out there and believe it or not, Berkley actually claims that Berkley FireLine Ultra 8 Superline is four times more abrasion resistant than its predecessor. I haven’t put on my lab coat and performed experiments with it, but I can certainly vouch for its toughness. I’ve been fishing a wacky rig around some gnarly wood cover while testing this line and it has really impressed me. Now, if you saw it across a jagged boulder, you still might have some issues simply because it’s braided line.
With that being said however, this stuff has some serious shoulders to it. I wouldn’t think twice before using this line to skip 10 feet underneath a boat dock; I’ve gained a lot of confidence in it.
