I found a Crown large at REI yesterday and a Blaze small.
I'm a 19" torso and the large was way too big, the shoulder straps were sewn to the pack ~ 2" above my shoulders. It had a M hipbelt and I had to pull the straps all the way for it to fit my 30" waist - with an empty pack. With 25 lbs in it, it might have been too big.
I didn't load either of them as they didn't fit, but in regards to padding, I'd say the Blaze hipbelt is twice as thick and twice as rigid as the Crown hipbelt. The Crown hipbelt had a better fit somehow, at least with an empty pack.
The shoulder straps on the Crown are just a bit wider and a bit more rigid than the Blaze, but also flat and less thick.
The Crown back frame is pretty flexible. The Blaze back frame is more rigid, and flexes less. The Nimbus suspension doesn't flex at all - for comparison.
The Crown large had about 2-1/2 lbs on the REI scale.
Hopefully I'll find a medium Crown in the future and load it.
