This has is the best line I have ever used bar none...I used Vicious once in the past and for some reason, I did not think I liked it. But fellow Boc Member H20 Mellon Brought me a 2-lb spool of the vicious off shore line, 30-lb test in high vis yellow. I spooled up a couple reels with it and on the first cast I noticed something very good! The line came off the spool smoother than any line I have ever used!. I use 12 foot rods for long distance casting and I was also getting about 10-15 yds more in my casting distance with less effort. Something else amazed me, I fish in areas where I have to reel my line thru alot of sand, and this line after using it several times has not had any damage due to the rough conditions. I always use Berkly big game, and usually have to change my line every trip or to, because the line would get very rough, not the vicious, it has stood up very well. so I can see changing my line much less. Vicious is also a copolymer line like suffix, which has a soft inner core for flexability, and a hard outer shell for abarsion resistance, it's like mono, but better. I give the Vicious line 2 thumbs up, and I hope I never have to go back to big game again.
