No quibbles with the tent or the pocket rocket - my first tent was a Kelty 2 person dome and I still use the pocket rocket. But the pack is huge. A 4000 cu in pack is plenty big for a luxury oriented backpacker, even one taking girlfriend gear. I carried the kelty, a quilt, and the rest of my gear in a Terra 40 pack (3700 cu in) and I tend to be on the heavier side of lightweight. One of the "ultralight" Gregory Z packs was one of my possibilities for a winter pack, when insulation weight would go up and so would the bulk.

Figure out your gear, how much it weighs, then go try on some packs with either your gear or the equivalent in sandbags in the pack to see how they carry. I had to move on from the Terra 40 because the frame didn't work for me even though the space was adequate. I think the more weight you intend to carry, the more critical it is to get the right pack for the job.
