Zebra mussels also rip braid to shreds. Not relative to many ares of the province but the sea is full of corral and other shells that rip all types of lines to shreds.
I love braid (or superlines), use them just about all the time and spools last years before I flip it around and continue to use it for a few more years.
But, it doesn't hold up to heavy abrasion the way fluoro, or even mono, does. That's just the way it is. If you don't need it, great, don't use it, I only use it when I have to.
Braid doesn't stand up to sharp teeth the way a good fluoro does either and there are lots of big, and small, fish in the sea with teeth that make a muskie look like a bass.
