To a certain extent (very close actually) I think Steve is correct. But, mindset should transcend technique. I recently got 3 classic WWII combatives books: Kill or get Killed, Cold Steel, and Get Tough. Especially with Cold Steel, you see that your killer instinct translated into technique is what saves your ass. If your mind is trained adn you can turn on and off the killer instinct/aggression, then you will use your techniques well, for the most part. You'll pick up a chair and smash it into that guy beating on a girl and be fine, you know? Sure, soem punches and kicks and weapons and such are better than others, but really, there are a zillion techniques that are good ones. I think that by getting the mindset right, you don't have to worry about technique so much. All you need to worry about is who's gonna clean up the mess when you kick your killer instinct up to level 10 and blast down some rapist's throat.
