Just got back from HD (Pittsburgh Area) where I picked up a
sheet of 3/4" Maple plywood for $30.
Both sides were sanded nicely and look great, clean edges also.
I believe it has Birch in the center.
They've had 3/4 Red Oak & Birch for a while ($40), but, this is the
first time I saw the maple there.
You are correct. Both outside layers are paper thin. Further, I
believe it is a mixture of Birch with Maple. Nicely sanded and look
great with slight imperfections on one side.
I bought a few sheets and now having trouble keeping the layers
Well, that's why you're using plywood, but it still doesn't answer why
you're using the more expensive Maple-covered plywood. I was just curious
in case I missed something. BTW, MDF might solve your flatness problem.

MDF will chips or worn where the router plate's adjustment screws sit.
I have used two 4'X8' plywoods. The first two set (3/4"X27"X41") bow
in the center and cut another two set and STILL bows! So, I ended up
using the first two (bow) set. Sanded it down (That when I discovered,
the outer layers are paper thin). I still did not get 100% flatness,
but I guess it will do for now until I cut the hole to fit the
router's plate in a few more days (WIP).
In the end I spend more and have more headaches!
