Well I do Kali Arnis Escrima, I am doing it for 3 months now, I train it for 6 hours a week. It's a complete system. I also do Wing Tsun 6h a week. I personal prefere WT. but that's just because I believe in it's effectivness. What I am trying to say, it's good, real good. Like most MA, you just need to train hard.
