Identical outline, dims & volume distrib, machine cut from the same scan of a shape Makani did for me a year or so ago.
The one on the left is (Bennet) PU foam glassed 4+4/4. The one on the right is (Marko) EPS foam (1.7#), epoxy glassed 6+4/6. The epoxy feels like it weighs less than half that of the (light) PU!

The poly has about 4 sessions on it and goes unreal.
The epoxy is still virgin no wax on it. When I take its cherry I think I will have as close to scientific evaluation of weight - performance as possible
