I have one of those and I like it a lot. I already had my gear and the pack was given to me, so I didn't really get to take advantage of the advise given here.

Instead, I learned how to use the pack with the gear I had. It took some time, I packed and repacked, went online and read about packing a pack, went to Osprey's site and watched some videos about it, and I finally got all the stuff I needed for a 3-nighter into it. It's full, but still comfortable. That was a bass ackwards approach, but it worked out well for me.

The things I had that helped make it work for me are a down sleeping bag that compresses well, a small, light, tent that doesn't take up much space (homemade), and a small kitchen and stove (I use a "supercat stove"). If you have those you'll probably be fine with the Osprey Talon 44 for the trips you want to take.
