How big are the windsock's?
How bright are the LED lights…were they visible during the day or solar charged and operated only dusk to dawn?
In the rules for marking cable spans I saw no mention of windsocks. and markers seem to be mandated 200 feet apart. and be 36 inches in diameter. I could find no diagram specific to slacklines.
