Simultaneous Block with Counter Punch

http://youtu.be/U8fVJE_EIig

I perform this drill with three different types of impact. In the first set, I counter to nothing but air. In the second set, I hit the bag on an angle that makes it recoil from the blow. In the third set, I hit the bag so that it has no where to go. My counter looks the same in all three sets but the feeling is very different.
