I still have the Detomoso brand as shown below, however they are pretty stiff. It has not caused a problem yet, and I suppose if they are built for a wing and non wing car, then the actual pressure on the decklid and engine bay hinge is the same, wing or not.
About hyperextending your deck lid, watch out! you could drive the top of your deck lid into the body of the car, so just watch that area if you are doing that.
