How are the cubes going to be for the national competition?

I've been to several qualifying competitions(I'm already qualified) but some competitions have holes drilled into the corners of the cube and others keep the cubes hollow. How are they going to be done for the national competition? The cubes with holes are near impossible to lift and I have heard news of Sea Perch making changes to the cubes to make them lift-able but judges say otherwise and it makes zero sense to me.

We've been practicing using the cube design with holes, as shown here on the SeaPerch website's build documents for the Challenge.  They were tough to lift until we added the backer foam pieces.  Once we added the backer foam, we had pretty good success with the challenge.  We built 3 sets of cubes this way and practice the challenge in a small swimming pool we have available on our school campus.

At our regional competition (Dallas), the cubes had no holes, and they seemed to "float" around more and were much easier to lift.  My students actually complained about them because they claimed they were TOO light and threw off the balance of the ROV with a cube.  Nevertheless, we were able to put up some pretty good scores in the 20-25 range on the Challenge, and finished 2nd and 3rd overall in the event.

Unless we hear otherwise, I suppose we should work under the assumption tha thte National competition will use cubes with holes and backer foam like the ones shown in the build documents.
