Just keep in mind though, that the entire reason behind the real world usefulness of Judo,BJJ,Boxing,Wrestling, etc. etc.is the ability to work technique at full speed and practice with genuine resistance while minimizing injury. You simply won't recall/be able to use any real technique unless you have performed it under stress and resistance many times. That is what combat sport gives the practitioner, and it can't be replaced with any amount of theoretical or low resistance sparring. Or even good resisting sparring for part of a class one day.
Not to mention that people forget how much less an eye or nut shot matters against an opponent flooded with adrenaline. People have been stabbed and shot in serious fights and needed to be TOLD they were injured and should lay down.
If you are really concerned with personal self defence, get a knife and learn how to use it, and spend a fair amount of time learning to run fast. 99% of "reality based self-defence" taken care of right there.
Addressing the efficacy of KM ground moves, like I said it doesn't matter how good they are. They could be team taught by Dan Gable and Rickson Gracie and it wouldn't matter. Unless they are drilled and practiced hard over and over and over and over until you can do them right with no warning or concious thought. If you haven't sprawled a thousand times for real, god help you trying to use it right in a real fight.
