I can see if you get an outside two on one against someone who is lighter than you, and they don't know what to do, you can cause do some damage. But, if they aren't feeling pain, it is going to be difficult to disarm. Regardless, it is very difficult to get to that position, at least when we train it at full power, speed, and resistance. That is my experience, others feel different. Best to try it youself (many times) at full-tilt.
I have no experience with Sayoc Kali. I would have to see it under Dog Brother style sparring to see what tactics and techniques they use under pressure. I would like to see that, as I am sure they have good ideas. Aloha!
