I core everything hatch wise with airex t92.100. Primarily because it is easy to work with and has good properties. The core, with the exception of plywood offers very little in terms of added structure. Dirtwheelsfl said it, the thickness is a driver with any cored structure. If the thickness of the core doubles (and the skins stay the same) the strength goes up 4 times as much. If it triples in thickness it goes up 9 times as much. The key is adhesion to the core to get the most out of it.
