Re: Backward Roll - Risks and benefits
In Shodokan Aikido we just don't do them and I think the main reason is safety.
In both kata and randori there tends to be a lot of very strong forward projections and the risk to the neck is just too great.
From a self defense point of view a backward role puts you in a vulnerable position whereas an ordinary back breakfall puts your legs between you and your attacker. Yes I'ld rather stay on my feet but if I have to go down I'ld rather be able to kick out than have my back to the person.
