Best pack for multipitch

Hands down, best pack I've ever used on route is the Tufa Mochilla.

I’m a big fan of the Patagonia linked 18

I just ordered one of these: Mammut Multipitch chalk bag so I don't lead with a pack. For long enough routes my wife will wear a small camelback to carry extra water and food. I can clip everything else I need on me. 

I dig my petzl bug

I just ordered one and now patiently waiting!!!

I'm a big fan of my Petzl Bug. In fact, last year I posted a question about it here on Mountainproject and received overwhelmingly positive responses from bug owners so I went ahead and bought it. I've since taken it to Lover's Leap (several times) and Snake Dyke in Yosemite as well as cross-country trip to the East Coast and international one to Barcelona. I just love my Petzl Bug.
What makes it stand out from other multi-pitch packs is the ability to comfortably clip a rope on top of it. It's a good feature for those long walk-outs after the climb.

I'm very happy with the Mammut trion light. Got the 28 for long days in summer, and the 40 for winter alpine stuff. 

I climb with either the tufa mochilla already mentioned, or sometimes a grivel lynx.

+1 for the Petzl Bug. Super comfy and secure to wear while climbing, rides high so that it doesn't block the gear loops on your harness, top and side cinch straps that work really well to secure a rope for approach and walk-out. I like that the daisy chain for attaching gear to the outside of the pack is centered so that weight is balanced. Holds my 3L camelback nicely, though it does lack a loop or hook on the inside to clip the top of the camelback to keep it upright. I fixed that by rigging a little loop of accessory cord through the haul strap and poking it down inside the bag through the hydration hose outlet.

I really like the DMM Zenith. I find it rides well above the harness and the main compartment access is pretty fantastic. Comfortable and breathes pretty well. It's super light with some thoughtful features. They're coming out with a new version soon that's supposed to beef up the fabric and maybe some of the zippers? Though, i find the current version to be pretty great.

Throwing this out to see if anyone responds: has anyone tried the Multi-Pitch packs from MHW? Curious what opinions are out there from folks who've clocked some mileage with the packs. 

REI flash 18 or flash 30

I like the black diamond bullet. Small and simple, seems basically identical to a petzl bug which a few people have already mentioned

If I need a small pack I go with the bd bullet. For my larger pack I just picked up a blue ice warthog 30L and it's sweet. I've got a short review explaining my impressions of it after a use, it's here on the forums.

I looked at the Bullet. I think the big differences with the Bug is that the Bullet prioritizes durability of fabric and streamlined / removable straps so that you can easily haul it through chimneys or over roofs. It has fewer straps on the outside to get caught on stuff.

The Bug, on the other hand, has the external straps for cinching down a rope carried over the top so that you don't have to backpack your rope, and the external daisy chain for attaching gear. It prioritizes comfort and convenience on approaches and descents vs. haul-ability.

I can say from experience that doing a long or scrambly approach with the rope slung over the top of the Bug is about a thousand times less annoying than tying the rope directly on my back. But I haven't hauled it in a chimney yet. 

Eddie Bauer Bacon. But i do everything in my power to never take a pack.  I only will if I am bivying.

I must admit, tying the rope to my back over the bullet is pretty annoying. That rope strap is a feature I wish I had often. 

If you anticipate having to haul your bag up chimneys or over roofs, go with the Bullet.  It won't snag, and it won't tear.  I agree that at times you wish for the attachments, but when the mission demands durability, the Bullet responds.  It can handle hauling a heavy rotary hammer drill for example.

If you anticipate lighter duty, I am sure there are lots of other satisfactory choices.

No pack is best pack
