Was this a qualified line test?

sunline mono

Is that the yellow stuff that floats?  I tried some once but couldn't figure out how to put it to good use.

sunline super natural mono,,,,,, but think it's a nylon blend 8lb dia.009 same as 6lb in most,,,,,,,,

I don't know about the Sunline Mono, but Sunline FC Sniper flourocarbon is good.

Hey Steve, a good use would be fishing with it.  You're welcome for the tip.      Dominick

if it's floating hi-vis mono, it's prob. float line: for long drifts -- not casting
I mean, you can cast, but small diameter/distance are NOT the point
it's supposed to sit on top & come off the surface better for mending/hookset
I'd expect less memory & slower water absorption, too
can't use regular mono that spirals and/or bows under the surface when water-logged,
between rod-tip & distant float

No it's a clear Japanese line,,,,,,,

sorry, not your Sunline, Benni... 
Steve needs a use for " yellow stuff that floats"
if his is a dedicated float line, should be this or much like it:

Also, found an old spool of J-Braid, "x-4". It's PE#4,  40lb.,  0.29mm. No "Grand" on the label either. How strong is this one?

X4 is a fair bit more accurate. No idea why. 41lb is what that line is rated in the European market.

I thought it was going to keep my line off the bottom and reduce snags.  It was a bust and didn't behave anything like I imagined.

In order to float they had to reduce the nylon density.  Reduced density means the line is fat compared to regular mono of the same strength.  Big fat mono doesn't cast very well...  especially compared to spectra.  

I also tried using it as a short top shot.  Jig to floro, floro  to Sunline, and Sunline to spectra.   The Sunline-to-floro knot did a lot of clicking and clacking trying to cast through the guides.  The Sunline-to-spectra knot slowed it down even more.
