Power hunter, I think. There is even better stuff than that though. Look for the 10x stuff. Refers to the number of woven strands. Most good US stuff is 4x. If you've ever handled cheap rope next high quality rope you'll know the difference. I had a good ebay retailer, I'll try to look it up and PM ya.
Ultimately your line, hook, and swivels (if you still haven't learned to tie a good knot
) are the connection between you and the fish. A weak link there will usually be exposed at the worse possible time.
