Barring anyone finding some nice HD documentary footage that fits the bill, I would imagine your work presents the best option for tweaking that ESB shot.

I think you're definitely right on this. The only thing that has been suggested and not reported back on yet is the Planet Earth documentary. (I've asked a guy I know who has it if there's anything like what we need) Haven't seen it, but I have a feeling that if there are any shots like what is needed, it'll be the type that's shot on a really sunny day with tons of glare coming off the ice, which is beautiful, but no good in this case. ;)
