Nick,
This wood sounds like a few planks I got from Stan Chilton when he
was unloading a heavier than specified shipment from New Guinea. They
are milky white with very straight uniformly dense grain. It may be
just my planks, but the grain "pattern"/"texture" reminds me of Luan
(fake mohagany). Mine are pretty bendy pretzels so they are used in
carved props. As Stan noted, it's beautiful looking wood.

I've heard another tangent to the "genetically modified" story where
real planes are using low density balsa in decking composites. An
Austrailian manufacturer does market these for alternates to phenolic
honeycomb/carbon composites.
