I have used the badlands 4500 and superday as well as this year the Tenzing 2200 really liked the Tenzing but looking around before I try their big packs for Bivy!!
I have the Blacks creek Canadian and i love it. The best feature is the expandable meat pocket. i can easily fit half a deer or 2 front elk shoulders in it. Havent had to put more in it yet due to having others there to help but it seems to handle this much wright just fine.
Black Creek looks like they have some pretty nice packs for reasonable prices - sure a little higher then others but I'm guessing you get what you pay for.
