Magnus I agree with you in some regards but Hamid is saying 'armlocks' not just an armbar. Judo gatama waza are brilliant for disarming knives (only to be done in real life or death situations!) and there are arm locks which can be applied standing (hara gatame, te gatame, and I forget the japanese for it but armlock under the armpit as opposed to stomach) all of which can be easily applied standing and you are well within your rights to break someone's arm providing you have an 'honestly held belief that your life is threatened' or if there is multiple attackers and merely subduing one would not be sufficient.
Even still yes I do agree with you Magnus when you can; an osoto gari (or osota guruma) is the perfect throw for putting someone down quickly and getting out of there, which 9/10 you should do when you can't run.
Oh I aggree completely and should have specified, but my point was that one should be careful what locks you do apply

Done Judo for over 4 years now, and the amount of practical techniques is tremendous.

Ude Gatami, if I understand what you meant you correctly?
I do aikido aswell, as it and Judo share origins, they mix very well

I used to be interested in the martial arts and application in the streets but i find the sparring side, and i think ill find the competition side, far more fun Cheesy Which is why i want to join the judo centre. It is a competition based centre so lots of sparring Cheesy
Definetly! Sparring,comps etc is alot of fun

I never did any style because I wanted to fight on streets, but alot of sparring etc, will give you seldefense ability.
