So the PDE Org. teaches "classical Derobio" while the "other" schools do not... Am I getting this right? If so, what is classical Derobio? Because in the PDE website, it is said that GGM Pedoy after being granted the mastership of Derobio from Ablen, he traveled around the PI to learn other styles of Escrima... So I am guessing that what GGM Pedoy taught also had some elements of other styles of FMA that he learned which in turn was passed on to his students and family... Not just what Ablen taught him... Correct me I'm wrong... Also, who started the art of Derobio itself? Was it Ablen? GGM Pedoy, the Pulahans of which Ablen belonged to?
