I have been doing jkd for a couple of months.JKD classes are usually mon,wends,and saturdays.Ive never gone to a saturday class since i have no ride,and my sifu has told me that they only practice straight blasts on saturdays,well most of the time he says.Ive seen it in action but never got to use it...well now my sifu told me the next class he'll work on straight blast so im not so far behind
