Montane has introduce several new packs for 2013. Ultra Tour 22 - Torque 40 & Grand Tour 55.
I have used the Medusa 32 for the last year for 3-season overnight & multiple days and 4th season skiing & single day general mountaineering. I have found it to be the "perfect" pack - if there is such pack. My hiking is mostly alpine trail, off trail & 3rd/4th scrambling and love the tight fit. When including a FF DSLR, tripod and full filter kit, I'll be slightly under 30-32 lbs for 2-3 days. The Medusa is unbelievably comfortable with that weight for a 2 lbs pack.
I've recently been trying out the Anaconda 18 for lightweight fast day packing - I could see using this pack for summer overnights with thoughtful packing. Both of these packs are an "A+" on my list - might want to give them a look.
I'm looking forward to trying out the Batpack & Grand Tour 55 for a winter pack.
