I used it for the 1st time yesterday, fishing with l2p. Because it was the 1st time I've used it, I'm not giving up on it yet (though, its probably gonna happen sooner than later, thats how disappointed I am with this stuff). The line itself didn't impress me AT ALL once I saw it in action underwater. And like Garry2RS mentioned, the weave in this line doesn't seem as tight as other products SpiderWire has out.
EDIT: Come to think of it, I've got 2 reels spooled with this stuff... I might just use it as backing too!
