Re: Backward Roll - Risks and benefits
When I was in aikikai dojo, I used to do lots of backward rolls. But then the throws were less forceful compared to what my Yoshinkan brethens are dishing out these days. Currently, in my practice, I seldom do any backward rolls. Maybe as part of warm-up, but never in a middle of a high intensity jiyu-waza session. The risk are just too great as some posters said earlier.
However, some of my yudansha dojo-mates still do them, at their own risk IMHO.
