If you're buying your first climbing rope you need to know how to uncoil it properly the first time. If you just open the packaging and start climbing rope you'll put a bunch of twists into the rope. This will end up coiling and kinking up straight away and take ages to fix. You have to uncoil a new climbing rope in a specific way. It's hard to describe but this video shows how to do it perfectly. Some ropes like Mammut's are coiled ready to climb, and Edelrid's come in packaging that allows you to pull the rope through a hole and be good to go.
