Has any body tried the black diamond speed 30 for extended backpacking trips and if so what are your thoughts on it. I like the size, how it doesn't have all kinds of stuff on the out side of the pack to get caught on every thing, I also like the removable top lid. It's advertised as a climbing back, but it seems if it can handle that, it can handle a extended hike. Also my gear, including water and food is right at 25 pounds.
