Doug,

I forget to mention the following characteristics of foam.  Foam has 
material that essentially fills the area behind the skin layers  So once 
you add the skins, don't think of it as just thin skin layers.  It is then 
something completely different.

Honeycomb however only has structure where the webbing is.  You have cells 
that are just air, no support behind the skin.  The larger the cell size, 
the larger the area that is unsupported.  In this case, large cell 
honeycomb and thin skins in combination with point source impacts would not 
work well.  This illustrates why foam is better for such cases and also 
illustrates why some high end applications desire foam-filled 
honeycomb.  Honeycombs greatest attribute is that it is a core material but 
it is almost entirely air, so it is the lightest form of core available.

Thank you.

Sincerely,
Shane Santi
