I am looking at picking up a new pack for a thru next year. Right now it looks like my top candidate is the ULA Circuit which it seems like a lot of people love. Another pack that is a little more expensive but also lighter is the HMG Southwest or Windrider (same pack, just one has a mesh outer pocket, one is solid). I haven't seen a lot of info on these packs here or elsewhere except for a review on Gizmodo http://indefinitelywild.gizmodo.com/...340-1613834205 . Does anyone have experience with these packs in the real world on the AT?
