Braided line

I used to be a huge fan of FireLine, but after fishing with PowerPro 10 years ago, I've never looked back. MossGreen is my preference on color.

I LOVE Fireline on my baitcasters!  It's cuts thru the water smooth as silk when trolling but floats cleanly when bobber fishing.
I switched out to powerpro a couple of years ago and lost every salmon I hooked for months due to breakage before switching back.  Haven't lost one since.

Perhaps you got a counterfeit spool.

Quite possibly.  I picked it up at Dick's....

Just be careful.  Braid and rocks do not mix well.  If your going to be bouncing the bottom, make sure to drop down to some mono. 

I don't know have many breaks I had this year because I was dragging over rocks (bass fishing).  I lost gear and fish.

I use 50# Yellow PowerPro on most of my gear, though I am still running some moss green.  I buy it in 1200 yard spools, and fill a friend's reels too.  I like the yellow better as it is easier to see the angle the line is making with the water. 

Leaders are generally 20# Berkley Vanish Fluorocarbon line.

Next time I might go generic as suggested by Craig.

I use power pro. Unless you really need the line capacity or the thinness for deep trolling, I suggest using something in the 50 to 65 pound range for salmon.  It's just a LOT easier to handle in a cold wet environment and tangles are easier to deal with.   I typically drop down to a section of 30lbs to 50lbs flourocarbon with one section of lighter line so I can break it off in case of a snag.  To me the main quality of braid is the no stretch.  To others the thinness is good.  I have had problems with braid 20lbs or less breaking when sudden force is applied like setting the hook or jerking on a snagged lure.  Breaks much easier than the stretchy mono of similar rating.  So make sure you compensate with appropriate soft rod and/or drag setting and you will be fine. 

Has anyone given berkleys recently developed nano-fil a try?

I have it on a reel and no matter what swivels, leaders, or different baits I try, the line gets so twisted after about 5 casts, it is unusable.

Any thoughts or ideas about this?

Same results here.   It was the first and last time I tried using a super braid on a spinning reel.  If making high arching casts where the lure hit the water with a rainbow of line following in the air, it often resulted in wind knots.   Some almost impossible to untie
  Maybe I need to work on my rainbow casting technique
Happens each time a line comes out stating it is unlike any other and revolutionary.  At first I think "Sure, heard that a hundred times already"  then I think "If someone does come out with a revolutionary line unlike any other .... what are the chances they wouldn't state as much"  so I try it.
