I was working on my blocks the other day in my GOJU class amd I was thinking ...would this work on the street? I was suprised when I inventoried my blocks. There was definitly a pattern into what seeemed effective and what didn't. To me it came down to: 1.Did the block redirect the force quickly? 2. Did the block allow me to stay in contact with me opponent in order to counter?
I found that the beginning blocks chambered and used with closed fists might stop techniques but they aren't great for remaining in contact after the block. I found that the open handed blocks transitioned smoother to other techniques. I realize that I'm approaching this question from a GOJU ryu perspective. I would like to know some other opinions on this matter.

Thanks, Mark
