I have used it and it is very tough line, I got some in 0.17 diameter and used it for heavy pole work and found it very good. It has been available for a while now but it never took off over here in Ireland despite people saying how good it was.
It is made by Zebco, it is cheap as well.
Its a new one on me  i dont like to buy cheap line because thats one of the most important things to have quality. I remeber me grandad bought some line which he got cheap there was about 4 miles of the stuff automatic birds nest whenever you used it though lol  But nowadays the cheap stuff seems to be just as good as the more expensive stuff
