Same as Dave T - the twist on it (which was then - 20 years ago - and still is now) about the worst of any well known brand I've ever used. I lost count of the number of major birds nests I had due to the twist, which shouldn't have really happened, and probably wouldn't have happened with most other lines.
I know a lot of people swear by it and have never used anything else, but I eventually gave up on it after two seasons (20 years ago) and consigned the whole lot to the bin. Bought a spool last year just to give it a go to see if 20 years worth of development had gone into it, but I found it to be exactly the same and as frustrating as ever. Took it all off the reel and binned it again.
I now use Reflo Power below 5lb, Reflo Power Max 5 to 8lb, Korum 8 to 10lb, Berkley Big Game for anything above 10lb. For anything that requires floating line, I use Bayer Perlon exclusively (although I do have a stack of Drennan Float Fish spools which came in an eBay job lot).
