Hello,
I purchased my Toray flurocarbon line. I put this 6lb line through a few not so scientific tests to see how well it performs compared to other quality flurocarbon lines. I put it through a strenghth test and the results were great. I had a hard time telling how much stonger it was to the lb over the other flurocarbons I tested. I can tell you I had to pull hard to break it. I know without a shadow of doubt that it broke over 6 lbs. The next test I did was to see how stiff it was compared to other lines and the Toray Super hard was stiffer than the other ones I tested. For me, I can manage it on spinning reel just fine but I can see some poeple having an issue with this. Knot strength, I could not see much diffrence in one line to the next. I never had it break at the knot but on all lines they all broke 1/4"-1" from the knot. That is all I have for now. Thanks
