Living down here I can face the same problem. The ND2 filter could be a few stops more. A polarizing filter may or may not make the sky darker. It can also cut reflections from water and most reflective surfaces. You have to be able to rotate the filter to align it at right angles to the polarization of the light you're wanting to cut. That means you would probably want it in a good matte box with a rotating stage especially if the camera is in sunlight. The extent to which a pola will darken the sky also depends on the position of the sun so it's not a cure all for that problem. When it does darken the sky it also affects the look of the shot, increasing the contrast between clouds and sky.
I would have thought a ND or grad ND would be better for your problem. You can get combined ND & IR cut which would be important with the EX cameras otherwise you'll increase the IR contamination problem. Both ND and more so grad ND filters also need to be mounted in a matte box. In fact a matte box without a filter could help improve shots in strong daylight. I'd suggest adding a french flag and wings to it as well.
