Badlands packs are well built and lifetime warranty can't be beat. For whitetails I really like the Superday, and the Diablo is another good one.
It really depends on just exactly you want to carry as far as which one is best for you. I've sold everything from the Ultraday pack to the 2800 for people intending to use them for whitetails.
Eberlestock makes some great packs as well. Check out the X1 for your needs.
For a little less money, and also a great pack, take a look at the Blacks Creek Western pack. We have 25% off on them right now in the Sponsor Classifieds.
We can help you with any of the above brands. Check out the Prairie Traditions website from the link below. I'm out west at the moment, but have cell service and email now and my wife is home and able to take care of shipping.
