Definitely prefer to have weight centered higher. I shoot for between the shoulder blades, but probably rarely achieve that. It makes a huge difference in how far you have to lean forward to balance the weight. I have repacked the same load to raise cg and the results are obvious. Internal frame packs are more sensitive to loading, but can also get weight closer to your back than an external, generally speaking.
There are some rather funny statements in this thread.
Was that Steve Climber's statements?

Hey happy, how does one become the world's leading outdoor enthusiast? Is it the knowledge and skills, or the enthusiasm?
If it's the enthusiasm, I think our last retriever was the world's greatest.
