Derobio stressed economy of motion. GGM Pedoy always told us during training don't put to much florete in our garrotes. Wait for movement than counter with an equal and greater force. Derobio is a very old style of Escrima. GGM. Pedoy began learning the concepts in 1906 under Gen. Faustino Ablen. How far it goes back I cannot say but at the time GGM. said it was already old. I had GGM. Crispulo Attilio at my school for a seminar he demonstrated a counter drill. He went from student to another until he came to Bo, Chaz myself. Yes Me. I am not to old yet to learn new moves. Instead of doing the drill his way we went naturally into Derobio counter for counter moves. When he got to me he stopped in the middle and told me you have old Escrima moves, that is very rare. Derobio is not fancy. At the beginning the student seems overwhelmed but later realize the simplicity of the conepts , fine points and movements. The more you practice the simpler the moves become. It is like peeling an onion. Layers upon layers of skin until you the center and what do you find, nothing. The more you practice the more layers gets peeled away until you reach to the core which is nothing at all, void of any preconception of movement . At that point you can move freely and with out hesitation when attacked. You not there to hurt only th recieve and return with an equal or greater force. You defend with humility and not with hate, You move with and behind the power.
