I appreciate all of the responses, but, I feel I was a bit foggy on my question (forgive me, I work the 3rd shift), so I will try to clarify. Growing up, and working in the security field, I've seen and dealt with a bunch of encounters. I've never seen anyone use the hard blocks. The action seems to fast, where, your opponent is on their second strike, before the first seems to finish, or their on top of you, or you on them, in a grappling situation. The hard blocks seem to be designed for the drunk's wild round punch, where you have time to time it and shatter it with a hard block. Even tournament fighters as well as nhb fighters never seem to use the hard blocks, tending to parry instead. I feel that it is a more natural tendency to "swat" or parry an attack. So I guess my question would be for those who are law enforcement, security, or some other situation that calls on your skills to be used in a Real situation, on a regular basis. Have you used the hard blocking in those situations, or do you use the softer blocks?
Also, If the natural tendency is toward the softer blocks, and our founders came from a tough street fighting background, where hard blocks were too slow to deal with, what could be a barrage of strikes, forcing them to come up with "eclectic" systems, why would they teach in the old manner, that was abandoned?
