A bit pressed for time just now, but one thing I would say is that the Rocket has a surprisingly short back. The straps are long enough that this was not a problem for me, but the fit is definitely different from, for example, the Macpac rucksack I use on longer trips. It's a rather squat little pack, wide but not too tall, which is a very unusual profile. Removing the side pockets leaves a superbly sized central pack, though, of about 40 litres (2440 c.i.).
It's rugged and well finished, which was a concern and a surprise given my experience with Snugpak's quality in the past, and should take quite a beating. The sewn-in covers are a bit of overkill for the average user, though, and little touches like that make it heavier than it probably should be.
I'll wait for the review before writing further, lest the same ground gets covered twice.
