I'll put in my $.02 for the IPSCO setup. Preferable geometry. When the decklid is closed, there is no vertical vector, so it won't heave your decklid out of shape. Mine has a slight heave on the left side from previous struts. When you hit the lock button, it lifts on its own. Pricier, but worth it.
