What is the best composite to use?

I have been using a material similar to the divincell foam. It is about the same but it has pre drilled holes threw it in rows two inches apart and the holes on one inch spacing. It is easy to work with and bonds well, once the resin makes it threw the holes it locks it in place and makes the core super strong. Also it is a bit cheaper too. No marine structural foams are cheap but it is not bad for what it is.
