If you want to bore nonflying spectators to death, fly 3D. The nonflying crowd want to see high speed low passes, rolls, low recovery loops and spins and perfect landings.
I sincerely hope you are kidding. While low passes look cool, I have yet to see a single spectator not amazed by 3D. Seeing a 10 foot plane hovering is nothing less than amazing. At my field that is the thing that draws the crouds. When a plane is landing no one even cares. There is 0 excitement there to the crowd.
