@tommo recorded a blazing take on the circular fours pattern for the Instagram account:
He’s a textbook example of how you’d do this with wrist motion — and little elbow. As we’ve seen, these two motions can often work together for downstroke escape / DSX in the pronated setup that Tommo uses, since elbow is DSX in this form and so is wrist deviation. The switching to DBX even at these speeds is really pretty awesome to see.
Tommo is fond of saying he learned this stuff from us but we can’t take any credit for this. We didn’t even know this slick combination of wrist motions even existed a few years ago, let alone how they worked.
