Looking through some of kach22i's threads and sketches I have come up with three different options for the wing/spoiler I would like to design. I will be using it in conjunction with the half tonneau. What I'm not sure of is how each design may or may not affect the low pressure created by the eye of the vortex that the half tonneau needs to be effective. Particularly, how the side profile of each design affects that vortex. Does the side profile move that eye rearward or lessen it's strength?

These are the three ideas I am considering.
