I currently have an osprey exos 58 that I like a lot, but I think it may be a little too big once I send my cold weather gear home and I think for the weight I should be at that frame less is the way to go. I have had my eye on a ULA pack for some time now (CDT or Ohm) but just recently the golite jam went on sale for 70 bucks. I've heard good things on both sides, but not from the good knowledgeable folks on white blaze. Thoughts?
