Can't answer your question, but I will say that B&H Photo (which you linked to) is a top notch outfit, with knowledgable salespeople. Just a satisfied customer. Give 'em a call, they'll know the deal.

I worked for B&H three years ago and I called my friends who sell binos there and they recomended Night Storm due to the manufactures warranty, size and field "servicability". Reason I asked you guys first is because I put practical knowledge over "the counter" knowledge. Those guys use high end stuff so much that they won't even bother with the lower spectra.
