The Trev is a lot of expandable foam over a honeycomb tub, right? I like that approach because the foam offers energy absorption with light weight, at least until the foam absorbs moisture out of the air, then it could gain a few pounds.

My biggest concern with their method is the formers that guided the shaping of the foam, which appear to extend to the fibergkass skin. One of the people

There is a bit of a raised line on one where the glass crosses a joint in the foam underneath.
