Got my Granite Gear Nimbus Ozone today. Went through the instruction manual. Took it all apart and put it all back together. Threw my gear in it. Total weight in the low-20s. Hoisted it on my back and took a few turns around the cul-de-sac.
I think this pack is going to be a winner. Let there be hope. The volume is noticeably larger than the Vapor Trail. Yeah, it's a pound heavier than the VT but there's so much more support. The internal framesheet gives a great fit to my back.
For those just starting on the journey to "light", (ie., how I describe myself) this pack warrants a look. Simple, clean design; outwardly it looks a lot like the VT... just a bit bigger. This pack will be in its stride with a load of 30 lbs., while the VT will be at its limit.
