I love Judo, and think it's an effective martial art (and not only in competition), but I have my doubts as to its worth as a form of self defense. I don't doubt that the moves are effective, lord no, Judo throws happen like lightning and off the mat they are not something you get up intact after. However, we don't do training for their use on an attacker, and even being able to Uchi-Mata in under a second doesn't mean you can remember you even do Judo should some shaggy bloke come at you.
Now, Pangration....
