So I see the XBull winchline says it's sk75 (sk?) Dyneema. Is it good quality or a false sense of security? The strength is rated way higher than the high end ropes. I just got a smoking deal on an arb bumper ($200) and a brand new never used Warn m8000 ($500). I have RE 4.5 coils. I want to save any weight I can (no the ARB doesn't weight much at all despite popular belief) so I'm thinking of switching to this line for my once a year use. In the meantime I'll save up for high end line if I necessary. So anyone use it or test it? Will I even notice the 20 pound weight difference?
