Well, it's been about nine months or so since I initially evaluated the Tuf-Line braid. Guess what? I have not changed my opinion one iota. It may be because I use copious amounts of KVD Line & Lure Conditioner that I have had very few problems with the line. Initially, I was surprised with the line twist on my spinning gear, but after several outings, and dragging the line behind the boat after the trip, that the problem went away, and the line started performing as what would be expected from normal braid, with no break-down of the coating. Further, several weeks after posting that I was unable to produce the backlash from hell, I was able to accomplish it. Generally, I fish with about a six-foot flouro leader on the end of the braid. Well, due to my own inattention, I threaded my line beneath the eye and through the foot of the the second-to-last guide on the rod. I don't care what knot you are using, the braid to flouro knot does not go smoothly through the foot of the guide. I made what I thought would be a long cast, only to see my lure land five feet in front of me - and my reel exploded with the worst over-run I had ever seen. Normally I pride myself on being able to remove back-lashes. In this instance it never crossed my mind. My Tuf-Line was toast and I knew it.
With the exception of only two light-duty trout rods, all of my reels, both spinning and baitcaster, are spooled with Tuf-Line. Yes, if you are not careful to thoroughly wet the line when tying a knot you can see the coating break up a bit, but, according to the manufacturer, that does not affect the strength of the knot. I wouldn't know. I have never had that problem.
Could it be that the KVD I use makes the Tuf-Line more flexible? I have no idea. All I know is that the formula works for me, and I would recommend it for you.
