Great video, easy to understand, very clear and detailed :D
I love how you guys talk about the smaller stuff.
The only thing would be how to pull his arm across his body. (i.e. the best angle. For instance, an armbar video explained how, instead of muscling the submission, bar his arm at an angle higher than his shoulder so that weaker muscles are in work on his side, giving you the tap) You can't always muscle that one, or at least I couldn't while trying this out on my brother. (We did it very very slowly, and he put on a thick jacket as a gi)
Do you guys do no-gi videos too?
