Gregory Z55

My Gregory Z55 pack has just arrived from REI in the US. I have had a quick look over it and perfromed the obligatory 'pillow pack' to check it's shape and size. I love it!
I was just about to buy the Osprey Atmos 50 when I saw that Gregory had updated their classic Z pack with this brand new Z55 for 2007 and it features an 'anti sweaty back' system (my phrase, not theirs!) just like the Osprey, but seems easier to pack as it does not curve into the pack space as much.
It's not an ultralight pack at 1.5kg (3lb 5oz), and two or three ounces heavier than the Atmos, but there is a lot of scope for lightening the Z55 as it is pretty straptastic straight out of the box. But is is 55 litres as opposed to 50 for the Atmos.
The reason I went for this instead of a Granite Gear or another lighter pack is that it's comfort zone is good up to 35lb, so with my base weight of 20lb and a weeks food, this should be just about right.
Info on the web is pretty sparse at the moment as it's so new, so once I have had a chance to have a better look, I'll get some photo's up if anyone is interested. You can check it out in full 3D glory here.

Now if this weather would just dry up a bit, I could do with getting out!
