LOL, when did you start doing the RAT? Before you entered the military you were starting to get really into Nick Cerio's kenpo system. Looks like you've evolved.
If you don't change your stance your not really doing the straight blast, your doing it more the wing chun way of chain punching. I personally like to run into my opponents. Remember the blast is all about pressure. Really blast in there and pressure the guy so he gets off balance. Then go into your clinch or take down.
