I'm not sure if it's "better", but it's definitely a viable alternative that will allow you to do some things differently.

Keep in mind that there is practically NO structural value to foam at all. Foam is there for one reason: to hold the sheeting in place, that's all. Open bays like I do works fine structurally, and removes mass from the tips. this has a 2 fold advantage: it makes the wing lighter, and it moves the center of mass (or panel CG) inboard. The effect this has is most noticable in snaps and spins. Snaps break on a dime and stop FAST. So, it's much easier to score well and control your snaps and spins.

You can still vacuum the wing using this method, but you have to vacuum the whole shuck, not just the panel. It still works very well and produces a really light wing.

With all that being said, I'm trying about 6 or 7 different techniques right now on my new planes. I like spars in my wings which adds an ounce or so, but these wings do NOT break.

At any rate, good luck.
