I studied under GM Rene Latosa, starting back in the mid '80s back when he taught 'PMAS Combat Escrima". Now it's known as "Escrima Concepts". GGM Angel Cabales was Rene's first instructor and the Latosa system still conserves many serrada movements although considerably altered to reflect Latosa's emphasis on power, "directness", and simplicity. I know that there are a lot of politics and bruised egos among the different groups with connections to Cabales, Sarmiento, Revilar and other great names inthe FMA's. But out here in the sticks, Phoenix that is, we're happy just to find another player! So, if you stay with a broad interpretation of the heritage of serrada, I guess this is the place for me to be posting. Any other Latosa Concepts people out there? And the rest of you guys...care to weigh in?
