Here is a rare video of one of my most talented training partners William. I was fortunate to train with him for many months privately. A few things that we focused on was mixing Japanese Jujitsu and elements of Aikido into my Art. Since those were his specialties at that time. We were simplifying it to be functional. In clinches with no gloves etc. (Here I am feeding him movements in a cooperative way of training, then later to incorporate it in non cooperative sparring) cooperative training is important to develop flow from technique and transitions without hesitation or awkwardness. Smooth and precise biomechanics.
