Has anybody used these new braids before?  I just bought some ProMix.  It was cheap enough.  But haven't used it yet.  I'll report more later what I think.

Have the 131, 40 pound test on a 2021 jdm zillion. Seems to handle pretty well, holds a leader knot with no issue from what I’ve experienced so far. A bit loud through the guides compared to the super slick v2 I normally use. I got it for free, probably wouldn’t pay retail for it. Doesn’t really stand out compared to super slick or sufix 832. 

I'm liking the ProMix braid now.  It doesn't handle as well as Sufix 832, but it does seem to hold it's color better.  It also floats better, because it doesn't have the Gore fiber, if that's important.  I got the 20# in moss green on a spinning reel, and so far it casts well, knots hold up, and the color hasn't faded in the least.  It feels a bit rougher and perhaps stiffer than 832, but I don't have a 20# 832 of similar age to compare it to, so that could just be because it's newer.  For the price, I think it's a good option.  It would be a great option if it came in hi-viz colors!
