Looks like MikBonsai was able to get some video of Graham Potter doing a recent demo, with excellent information & philosophy. The three videos are about 1/2 hour each, and the demo is a first styling to create primary branch structure. The question of when to start wiring & creating primary branches always comes up. Hope this helps.
A few issues with sound & video quality, but I popped in earbuds & listened like a podcast. The first one is all talk anyway.
