Re: Ueno Chimp Rolls
If the most common problem is for people just learning how to roll, then what matters is how easy it is to learn, right? And how damaging the most common mistakes you would tend to make would be? Not so much how they work once you do them well.
Unless there are more shoulder problems among more experienced 'rollers' than I'm aware of. If I understand right, though, I was under the impression that rolling injuries are mostly a problem of people during the initial learning curve, i.e., when the roll doesn't come out quite right.
