I found this line and it is certainly light and plenty strong and I'm wondering if it has be used successfully as suspension line?
This 3/32" (2.5mm) braided polyester and dyneemaź is perfect for guylines using line locs and/or mini clamcleats line loks. The cordage is weather and sun resistant and can be tied into knots. The right size to handle easily. Extremely strong for its diameter with a 450 lbs breaking strength and it does not stretch. It is tangle resistant. Comes in neon green and white (easily visible).
