I used 19mm on my 10", you might be able to use 13mm on an 8" and you will not save much weight going thinner as your cutting out relatively thin rings. Consider how your going to build your truss or strut structure. Struts are easier to build and you can still triangulate support bracing. Importantly you want to use a material with maximum stiffness if going with a strut, it is less important for a truss.
