Next build (Gee Bee QED again)

I am planning to start another Gee Bee QED build.

I've a couple of choices to make.
1) Material, EPP or EPS?
2) Wing airfoil, under-camber or symmetrical?

A few of the related parameters. I have and would both 3mm and 5mm sheets of either foam. The wing span will be about 30inches the flying weight should be 8 to 10 ounces. So I am not expecting a high wing loading. And I am not asking for a high speed. I'm planning to use a blue wonder motor and a 700mah lipo.

What would you choose for this project?

- Allen
