It's worth thinking about what kinds of things the pack will be used for. I used to have a walkabout 35 and I really liked it. However, when I started to do more scrambling and climbing I found that it wasn't so suitable because of the side pockets and general shape. Not that I'm knocking it, but it's worth thinking about whether the sac you buy is designed more for scrambling and climbing or for walking. From my point of view, side pockets are really handy in a sac that is used just for walking but if you're scrambling they get in the way and a climbing or more slimline running-type sac might suit better.
