The 30 feet gives you plenty to work with, and it holds a knot without slipping once you've tied it off. We've only used it a couple of times but it's already become a regular part of our nights in.

Wasn't expecting much for the price but this rope has a nice weight to it and doesn't fray after a few sessions. The 30 feet is plenty even for more elaborate ties, and it holds a knot exactly where you put it.

The 30-foot length gives you way more room to work with than the shorter coils I've tried, so you're not constantly re-tying between positions. It holds knots well and doesn't slip once it's set.
