The only video footage I was able to get on the HD was 2 days in April. It was very warm and conditions were not the best especially for carving and speed. I am much more comfortable in colder conditions which is where I have spent almost all my days on the snow.
The HD and its new profile is better for carving, perhaps slightly less playful than the CT though.
I was just surprised how you were really struggling to the get board to do what you wanted it to in the video.
I initially thought injury because you appeared to be riding without much flexion and, as a result, with not much edge angle. But maybe it really was just a limitation of the conditions and the deck...
