i've been considering a bonneville style spoiler myself, i didnt even consider the idea of sloping down, kicked around the idea of sloping up, but am thinking that i would try something flat. which when i thought about it, thats how they do it at bonneville, so it kinda made sense. likewise with the length, i think what you see on the cars at bonneville might be the best for aero, but i think at that length and limited profile (hard to see at certain angles) i could see issues arise in parking lots, backed into, walked into, door opened into, so i dont think i would extend it very far past the edge of the bumper.
