I think alot of people forget that the amount of force applied is really unimportant, what matters is that you know where to apply it. For instance, a little bit of pressure applied in a spiral motion to the wrist (moving the pinky towards the thumb) causes the wrist to lock up and gives your opponent 2 options, to fall down or to have their wrist shattered. If you turn the wrist the other way it causes your opponent to come up off of their center of gravity and make the body easy to manipulate.
These are pretty standard Aikido techniques (kote gaishi and sankyo), but they are alot of fun to use and allow you to manipulate an opponent of almost any size.
