I've an old NF 'Clamshell' one called the Double Take. 40 Ltr ish. Very comfy to carry,all around zip, but now discontinued.
They do a 'Double Shot' model now, but the Arcteryx above looks a nice, if pricey sac too
I've been using this sack for the last couple of years, and wouldn't use anything else. The zip system allows it to be used as a rope bucket too, which is v useful. Gear racking is excellent, and if you have one, the Arcteryx Haku rope bag fits in perfectly.
Typical well made Arcteryx
Where are you going to put your tools? I've got the older version of the Miura - http://www.ukclimbing.com/gear/review.php?id=3906 and I used to use it for icefall cragging in Finland but it has more straps on the outside than the newer version, which hold ice tools ok. But its very heavy and tough, not designed for climbing with at all. It just sits at the bottom of the crag.
Not sure if it of any use to you or anyone actually, quite a niche rucksack but my mate tested this for the North Face and he reckons it is the dogs nads:
Lowe Alpine Eclipse 35 is a decent pack. It's just 35L, but rather big 35L.
It's medium weight of 810g. Has loops for axes and side straps for skis. Only problem I have with it is that it's difficult to attach a tent in the middle. The option would be to put both skies on one side and a tent on another, but with my gear it gets disbalanced.
