Brad,
You know better than most how personal pack fit is. The straight frame the MR packs have has worked well for both myself and my partner, and this straight frame felt good to us too. The Kifaru bent frame feels good to me when I'm wearing it, but I usually wake up with a lower back ache the next day, don't know why.
The belt worked just fine for us, and as mentioned, far better than expected. I do generally prefer the MR belt, but not enough to not get one of these, as the package is perfect for most of what I do.
If you ever want to borrow one, you can try out what ever one I end up with, just let me know. I expect Kurt would be more than game to let you demo one as well, and the visit is worth it to oogle the sheep...
