There's been a whole lot of asking so far about how we find the RX ropes. We got our hands on some and simply said, it's one of the fastest ropes we've ever tried. The beauty of these ropes is that each is custom made for you so you cable trip don't get you. How long is enough? Follow the instruction here and if you are used to the common cable ropes we use at the box, get the Hyper 1.3 gauge (like the ones here). Looking forward to see high flyers!
