  The other difference between exterior (cdx ) and marine is that
most 5/8 exterior is only 5 laminations and most marine fir is seven so
it is stronger , also the glue would saturate the thinner plys more so
is more rot resistant . As Jim said , the plys in marine have no voids
, which might also mean a higher quality log , or a higher quality part
of the log - even if the voids are plugged with patches of wood or bondo
it would be better than an empty place for water to collect and fungus
to grow were one to show up on the edge you cut .
   Me - I spent the extra 25 -30 bucks . Which is a lot for
a Scotsman like me ! ( forgive my racist slur )
