Hmm, I dunno about Tooth NE slab being a "beginner" winter route if conditions are thin, which they seem to always be. I've been up twice and both times that traverse pitch was pretty hairball -- just thin ice over slab. If you're trying to avoid having to waste time bailing, I dunno if I would count on that route because thin conditions seem to be pretty normal
Add Colchuck NEC to your list
