Alot of people swear by the straight blast because it was rumored to be one of Bruce Lee's favorite techniques.

As suggested above, I still ponder that if you used more powerful punches within its charge, instead of series chain punches why not 1-2 fast hits & then a power shot. I wonder if all that tussling and the other strikes would be needed? Now its always wise to have a alternative plan, which is all I'm saying.
