I'm not sure what size the rope is. I was out experimenting with it today. My only minor complaint is the rope. Sure, I knew it would be cheap and I'm sure it's strong enough to handle loads within reason, but it's that kind of stiff, slick nylon rope, the stuff that isn't exactly easy to hang on to or fun to wrap around your hand. I usually refer to it as "boat rope."

If it were something I was going to use on a regular basis, I'd replace the rope with something more like a "climbing rope."
