Garret, I think a far easier and still light method is to foam cut the entire core and then just cut out lightening holes. A friend of mine did this with great success. You attach a thin ply template for the holes (the holes are rectangular in shape with rounded corners) on the top and bottom surface of the foam cores, and cut out the shape with a small hack-saw like hot wire cutter. This way the rest of the wing is still built as if it was a foam core wing, you can still sheet it, and a lot of the foam is removed.

I hope this helps,
Shaun
