Ive never studied NPM so I wont tell you what it is not. Instead I will tell you what SPM is. To say that SPM doesnt imitate the movement of the praying mantis is just plain wrong. The hanging out of the arms and crushing in/ripping out movements of the Sarm bo jin are evidence of this. The use of the drop fist also illustrates my piont. Also the aggresive and evassive tactics the mantis displays are employed in the system(Chow Gar). I have seen demonstrations of NPM and have to say that it looks pretty effective even though I dont understand a lot of the movements. I like to think of NPM practisioners as cousins not rivals. The fact that we have both claimed the insect does not mean that we cant share it. So to conclude the movements of the mantis are present in SPM just not as obvious due to the compact nature of the techniques.
