I wish I could love this Pack!

I bought the Women's 50-60 for short backpacking trips. I have the smaller Ducan Spine for say hiking and love it. I thought I would equally love the Ducan Spine 50-60 for larger loads but it just doesn't have all the features I find would be nice to have for a backpack trip like an outer mesh pocket (rather than an outer zipper to access the main compartment. Also, as I was cranking hard to tighten the cords, I tore the grommet off the rubber piece near the top of the pack as well as the rubber itself (this was only my 4th trip using this pack) - thinking it should hold up to heavy tightening over long term use. I have pictures of it i could submit. I do love the way this pack carries on me, the roomy/stretchy side pockets hold a lot and are easy to reach while wearing the pack. Also love the material - if there were a mesh outer pocket and easier to use straps rather than the draw chords, it would be perfect!
