We all knows that pine plywood do check, but what about birch plywood?

Here in the US, most of the good Birch plywood comes in from Finland,
Russia, and a few other Eastern European countries.
Most of it is sold in about 60"x60" sheets.
1/2" is actually 12 mm and is 9 ply.
3/4" is actually 18-19 mm and is 13 ply.
It is normally used by the cabinet makers because it is so stable;
however, it is definitely not suitable for exterior boat use.
It is beautiful stuff, especially the Finnish product.
