My plans call for baltic birch or finnish birch, I see Aircraft Spruce has finnish birch and domestic birch both meeting aircraft specs, the domestic birch being cheeper, can domestic be used or is finnish birch that much better? Also a local lumber yard (not a big box) has baltic birch in the 5 by 5 sheets.
what to pick whats the pros and cons.
