A couple of years ago I got a bad 600 yard spool of high viz Vicious line, it had weak spots in it and would break easily.
I called Vicious and they sent me 2 replacement spools, both the replacement spools were the same way.
I was a P-Line user till I got where I just couldn't see the moss green anymore, thats when I went to high viz Vicious, now that P-line makes a high viz, I am trying it out.
