I think Scott is talking about Spiderline Fusion, which is not the same as braided line. A lot of folks confuse it with Spiderwire, but it is not the same thing.
Fusion is a thermal line, is very tough and fairly resistent to abrasion. Even when it does get frayed, the remaining strands are tough to break.
It's cool stuff. It casts well, has no memory, almost no stretch, and it's thin for the strength it delivers. The only thing I don't like is that sounds funny going through the guides.
Jeanne and I were fishing with it today, and she got a crankbait caught on a submerged limb. We couldn't reach the bait, and decided to just yank on the line in hopes of breaking the tree branch before the line broke. The split ring on the snagged treble (on a brand new Rapala) broke instead of the line (Spiderline Fusion 10 lb). Like I said, tough stuff. I always make sure to have a sharp knife handy when I use that line, because it is tough to break any other way.
