As kbennett suggested, check out the Osprey lines, since you found a fit there earlier. My son has an Aether and finds it extremely comfortable, although it's not exactly light weight (he "sherpas" for his kids and since he's a surfer he also carries a wet suit to the Olympic coast), Go to the downtown (flagship) Seattle REI store for best selection. If that doesn't work, check out McHale. You do need to know your torso length, but that's not something you can measure yourself--the REI store will do it for you. Try to find a clerk who is knowledgeable about packs! (I always seem to get stuck with teenagers who know nothing!)

As someone who's on the short end for most packs, I can sympathize with your problems, even though they're the opposite of mine!

Good luck! I hope we'll see trip reports from Romania!
