What's the difference between the CMA side kick and the TKD side kick? IMO, the difference is the trade off. - CMA side kick use the shortest path for speed. - TKD side kick use the complete path for power. What's the difference between the long fist punch and the WC punch? IMO, the difference is also the trade off. - long fist punch uses 180 degree arm and shoulder angle for maximum power and maximum reach. - WC punch uses 90 degree arm and shoulder angle so the 2nd punch can come out faster after the 1st punch (less distance to travel). We can just consider that any MA style can use technique differently when different require is needed. The trade off doesn't have to be between styles. It can be in the same style. - A long fist jumping front kick without kicking the leg out is exactly the same as the MT flying knee. - A long fist 360 degree backward ground sweep is exactly the same as the TKD spin hook kick if the sweep is done in the air and on the head level.
