I always recommend that when new, you take the still bound rope and have a mate put his arms through the two loops at the ends.
Then undo the plastic staps or whatever the rope was bound with.
Then, from the one end, uncoil the rope into big loops on a clean floor (like Mod said).
Do NOT throw the whole thing down and start to coiling it from one end to the other. This actually creates bad rope coil twisting, and you'll have to climb allot before the coils work themselves out.
To undo the coiling, climb on one end, and when lowered to the floor, pull the end that was tied to you through the chains and climb with the other end next. Repeat 50 times and the bad coils might disappear.
Keep on swopping the ends and you might even add a year to your rope's life imho
ya dig?
