I guess I've been too conservative in my comments. I never intended to scare people off of c-c chain runs completely. I just want to caution teams against betting your season on something that has the potential to fail miserably if you don't know what you're doing.

How did it ratchet if the chains were properly tensioned? What defines "tensioned"?
