Why would you break it up....just keep moving until you get out.
I'd imagine if you kept going, and waited until you 'got out', you'd be overwhelmed by the other attackers - or if the person who has hold of you is inclined, you'd get taken down/thrown yourself.
This is why I have become disillusioned with aikido, at present: it's entirely theoretical - which I understand - and there is no provision made for when things don't go perfectly to plan: i.e., real-life.
Can you not use 'aiki' through other techniques - in other situations?
I really would like to see a new akido training methodology emerge, as the old one - as Jigoro Kano said - is severely lacking.
