"When in doubt straight blast". I think Bruce Lee is attributed with this phrase. When I saw these punches I thought they looked like Rabbit punches. I know JKD uses these too as well as Wing Chun.
The Straight Blast gym under Matt Thornton use boxers crosses in fast succession not this type of punching I am doing. That is really harder to do and is really committed body weight forward top half.
I know this punching makes people flinch at least. I throw in elbows too on the pads. The punching isn't an end in itself.
