I would have to agree with some of the other posts, and also ask how many times you've (a) been to the Presidentials in NH, and (b) how many multi-day winter traverses have you done? Of course, you probably know your own abilites better than anyone can infer from your brave post, but you're talking to a community of people here who one way or another live, eat, and breathe these mountains...lots of people and lots of passion within this community, and it's not hard to see that everyone here cares deeply about the safety of all the hikers/photographers/etc here.
The Presis are a beautiful, stunning hike, though!
Best,
Matthew
