I propose using whatever cord is strong enough, inexpensive, and compact, then marking it with fluorescent surveyor's tape. Another option is adding your own glow paint as needed.
I am not (yet) a slackliner, but I have been impressed with the methodology of testing and development of Adam Burtle of NWslackline.org. His site has a number of videos that demonstrate different...
Avoid the problem with a better solution Avoiding the twisting in the first place surely is best, and there is a simple way to do that: This is the Super Munter, Monster Munter, or Double Mun...

With dedication you could learn to climb at a top-rope or bouldering climbing gym without professional instruction. The key skill there is belaying, and you could learn that from videos. However ...

In the Top Gear Winter Olympics special Richard Hammond (and the car he is inside) are subjected to extreme winter conditions (-40°) at the MIRA test labs. Hilarity ensues. Top Gear segment: http...
It doesn't take -20°C to form ice near waterfalls or freeze curtains of water, though perhaps it takes that to freeze fast-flowing falls entirely. See this Blog entry from which these pictures wer...
Beal Ropes has a guide that covers this. Read the page but here are two images for quick reference: A robust half rope such as the Mammut Genesis is probably a very good choice; such a rope is...

You are apparently confusing static and dynamic elongation. You must use rope that is UIAA-101 / EN-892 certified for the task at hand. You will be buying a Single type rope unless you specifical...

You can largely mitigate the problem by braking to the front and keeping tension on the carabiner throughout by pressing the system away from your body, rather than braking to the side. Neverthele...
A carabiner is designed to be loaded only along the long axis, near the spine (leftmost figure below). It will be weaker in any other direction of stress. Primary long-axis strength should be mar...
