Re: Backward Roll - Risks and benefits
To answer the original question: IIRC I believe one of the associations (USAF-WR?) stopped doing backrolls a number of yrs ago because of a very severe injury?
Personally, in situations where I just need to deal w/ being propelled down, a backfall works fine, and if I'm being projected, some variety of the "mai kaiten" across the shoulders while turning in space and right back onto the feet works fine too. I stopped doing backrolls after my first knee injury in 1999 and never once felt that I "needed" them in my repertoire.
