Berkley X9 20 lbs Crystal. This line reminds me of Fins 40G in texture and feel except I can't get it to kink up like Fins 40G. This line is nothing like Fireline, Nanofil, or even Berkley Pro Braid. It's just a very soft very limp smooth braid. Berkley includes the European and Asian Specs. And the ABS tested right on the money at 37.10 lbs! Summary: ABS : 37.10 lbs Line Mass: 17.5 mg -------> Line diameter = .293 mm, no where near the listed .17mm S/W = 2.12 FG = 26.60 lbs = 72 % PR Knot = 31.90/37.10 = 86% PR knot came in at 31.90 lbs (86%), but the knot broke at the mainline and not at the PR Knot .I did the PR knot to see if I can kink the line. I couldn't but obviously the line broke 2 inches in front of the knot. I'm sure the damage is from the twisting of the line when making the PR knot.
