Lot variables there. How much are you going to carry? Is it all going in one pack, or are you splitting it up with your spouse? Are there any little rug rats? If so will they be carrying stuff, or are they to be carried? There are alot of quality packs out there most of the arguments of "Why pack A is better than Pack B" comes down to personal preference. I'd suggest figuring out how much needs to be carried and then go to a discount site like Sierra Trading Post (just Google it). They sell to backpackers and hunters. There you'll find closeouts on all kinds of stuff, (they have seconds too but I think they'll take them back if you aren't happy with the item.) If you aren't sure what you need (how big is a 2900 cubic inch pack anyway?) go to a local store, look around, go home and make your purchase.
