I would say that I love the line overall. Use the 6 or 8 pound on your spinning gear unless you have some large caliber reels (I use 12 on my BPS Pro Qualifier size 4000 with no problems). I really think it is superior to mono and doesn't have some of the negative properties of fluoro...it is strong, can be used top water (sinks, but not like fluoro) or under, and is pretty abrasion resistant.
Again, I would say all that but instead I'll say...the line is junk, you should send me all the spools of it for $1 each and I will safely "dispose" of it for you
