i think really that both these packs are way overpriced. price should always be a factor. becuase in the end, it is not the pack, the cams, the rope or the shoes in which allows you to climb, it is you.
i have a nozone in which i paid nearly nothing for. makes for a good pack. its only drawback the fabric is way lite, it gets holes in it. anyone tell you different then they dont climb.
i would buy something with more long term realiability. the lighter fabrics are not this.
