The underlying reason behind Kali/Eskrima was to avoid the restriction against locals from praticing/learning self-defense techniques. Those restrictions still exist today, but are accomplished in different ways.Orchestrated fighting which a lot of the martial arts have become doesn't impress me a lot.
There is a reason martial arts never really caught on here.
I have found it useful in maintaining hand/eye coordination and fast muscle response. It is not an end-all solution nor my first choice in self-defense.
