Let me know what your preference is (i.e. horizontal vs vertical). I think I'm partial to the vertical.
FYI - I used a 2-stop ND grad for this image, on a tripod, remote shutter release, polarizer, and mirror lock-up.
I also find it interesting (and I didn't know this when I was taking the pictures) how the water disappeared from the vertical image. Maybe the wind changed directions and I didn't notice. They were only taken minutes apart.
