Most interesting design path:

ToTAN. One entrance, several exits. It’s done so well, you forget there’s essentially only one massive ramp in the game but with clever diverters.

Most fun: White Water. Whirlpools to drop offs, hidden twists and turns, and the massive drop on spine chiller are crazy fun to combo.

Honorable mention: The Shadow, since you can not only choose what path the ball goes down, but you can also use the diverters to “push” the ball into the lane you want if your ramp shot was *just* slightly too weak to make.

Operation Thunder?

Honestly, the only game I can really think of that meets these criteria is White Water, but your aviation theme throws that out the window.
