I hope I'm not bugging you with these messages.
Every one of the things in the videos except for the application from the harimau box are ways to train your body to react in certain ways. With the harimau hands, it would be fast and easy to bring a strike to one side, attack the eyes, then attack the head/neck/etc, and the drill which is on the video is designed to teach you all the ways of hand movements and striking rather than be actual techniques.
The cimande arm strike things I think are ways to get past that first strike and into a position where you can do some damage, you don't need to scoop after you do it.
I dunno man, but I appreciate you talking with me about these and do value your opinion.
