i prefer to use the 360 cameras small and unobtrusive, so you can go where the viewer can't go and be right in the middle of the action. the bandwidth for sharp playback isn't there yet (at least not on main channel youtube) so using these big setups makes not that much sense. for now it's more about the experience.
this 360 for instance would be impossible with those big setups but it's a cool experience: https://www.youtube.com/watch?v=FK1zwHhwVNE
(agreed more light was needed there :) )
it's filmed with an insta360 camera on front of F1 driver ricciardo's go-kart.
