I don't have any technical data to rely on, only personal experience. I've fished about every line imaginable. All I fished for before 3 years ago was Walleye and smallmouth bass. I've fished mono, flourocarbon, hybrids, co-polymars, braids, etc...... Mean Green doesn't break off 1/2 way up the line like other co-polymars. The abrasian resistance is unusually high, and the knot strength (IMO) is far better than any other line I've tried. The true test I gave it was fishing it last winter in Lockport. The air temps were 14 F. Brand new spool of Mean Green. Not once did I have any coil in the line in cold weather. It remained limp and didn't stiffen at all.
The only downfall I've seen in this line is the availability. Never used to be able to find the stuff. But now......I turned a dealer onto it here in Ohio, and he can't keep it in stock now. Sells out very quickly to the cat/carp/saugeye/bass guys. Not a problem finding it now......as Wacker carries it. I've seen what Wholesale is on this line....(I used to get mine for a buck or two over it)......and Paul has a VERY minimal markup on it. Not making crap off it at all.
They have been around for years, but have been a small market. They don't produce in extremely large quantities like Stren, Berkley, etc. So there is more attention paid to what is being made (that is a positive).
