I have heard that Angel Cabales claimed that anyone can learn the "basics" of Filipine martial arts (escrima, etc.) in 6 weeks. Given that most FA martial arts teachers say the opposite ("train for 10 years, and then you will be intermediate", etc.), I am confused. (one reason is, they want you to pay fees for as long as possible, etc.). What do you guys think ? How much training do you need to be "pretty good" ?
