Vance will offer advice to enhance safety for gyro operations, but he's not punitive about it, and he's a true gyro guy (not a helicopter person), so I think your wrists are probably safe from assault from him.
Confined area operations can be demanding, but not necessarily dangerous if skills and winds are suitable. Looking at your video, I'd be more worried about the bystanders (including camera person) being so close than the area itself.
I learned to fly helicopters at an operation where we landed on a dolly, which was then towed into the hangar for storage. Putting it down on a dolly only marginally bigger than the skid footprint (especially for models where the skids are pretty far back from the pilot viewpoint) develops precision quickly, and I've always been glad I went through that early in my helicopter life. It made confined area work less stressful when I reached that part of the training.
