When was the last time anyone saw someone get a rib broken from a straight-scissor on the body? I would argue that I've seen many, many more injuries from hammers, wings, et cetera. Removing this technique would remove a lot of offense from a lot of wrestlers. I'm not even in favor of the wording in the book now. Some moves aren't very comfortable to be in....that's kind of the nature of this sport. The figure four on the head should be legal as well. If you're good enough to get there you should be allowed to use it.
