I bought a badlands 2200 pack in 2005 and still use it as my main "day pack". I can cinch it down so it doesn't feel like it's taking up too much room or cram it full of "stuff" if I'm on an all-day jaunt in bad weather or going a long way. Regarding pirogue's zipper comment, I've had the pull tabs break on some of the zippers on my 2200, Aside from putting small key rings on the zipper heads to pull with, they all still work fine after 14 years of heavy use. Note that I am careful with my equipment which may lead to having fewer problems with it, but with all manufactured things, there are some lemons out there.
The Badlands 2200 isn't a one-pack-does-all pack, but IMHO the best "day pack" I've ever used which can carry about 50# comfortably if need be. I've used it on rifle deer hunts packing my Zeiss 15x60s and Manfrotto tripod as well as the rifle in the rifle "pouch", and have used it extensively on archery elk hunts. I have an old Gerry internal frame backpack for carrying meat as well as a Kelty packframe with a "shelf" I added when needed. The Gerry is clearly the most comfortable for carrying a lot of weight (in the form of just meat), but the Kelty is best for tying on things like pigs, whole or half whitetails and the like,
Here's my recommendations:
1) Decide how much you really have to spend
2) Decide what you need most as in a pack for weight or a day pack
3) Figure out your limitations... not everyone can strap on 100# of meat and head for the truck...
4) For any pack you get, make sure it fits your frame. Even the daypacks should have the ability to keep the weight off your shoulders (internal frame), because if not, you're not going to be liking it very much after a long day on your feet.
5) Remember, carrying meat is likely only 1/10th of the time (or less) you're spending in the field. You may be able to get by with a good external frame for carrying the load if it has a very good waist belt system and good shoulder straps. Your focus may need to be on what you really need on a daily basis as that's going to be the bulk of your time in the woods.
One pack can do it all, but as Lance and others in the past have (accurately) identified, they're not cheap to get that all-in-one. Those are great for sure, but when you're in line at Bashas and you want to purchase groceries with a single $10 bill, you can't walk out with $20 worth of groceries.
my two cents...
