Paul, take this with a grain of salt but I recently ordered some 1/2" Baltic Birch ply (B/BB grade) for a cabinet project, once they unbanded the unit there was 1-2" of twist in each 5'x5' sheet. Even thin rips from that stock were pretty wild. I'd pick the plywood out in person for a project like this if at all possible. Some hobby stores have small sheets of 'aircraft' grade plywood, that stuff seems to be much more stable.
