Clayton,
Be aware that it doesn't matter how many or type of securing mechanisms you use. If you forget to latch them it won't change the result(see rookie mistake). the Dzus(?) fasteners are a spring mounted securing mechanism and won't tolerate a lot of stress(how much I don't know), but I use them on areas that are getting a down force from the wind such as the front nostril panel. Then there is no threat of the wind doing any damage. If the rear clip rises up the slightest bit it will be hit with the force of the air moving over it(negative at the rear window) along with the positive force of its face rising above the cabin, and the lifting force will be considerable(again I don't know how much). I use the Aerocatch system which is a pin system but is hidden below the surface. My rational for using them is that 1. if the covers are up in the air, are to alert you that they aren't fastened, and 2. they are lockable to keep prying eyes from taking a peak(it does happen). But as I said in the beginning, if you don't latch them, bad things will happen.
I guess what I am trying to say is that if by chance you latch the Dzus fastener and somehow forget to do the bottom latch, you may be putting yourself at risk when at speed. this from one who knows.
I am not familiar with the latches you are showing so if they can handle the load, then disregard that part of the information.
Bill
