I'm pretty sure Badlands has a pack that accomodates a bow.

I have a 2200 and it's one of the best packs I've ever had. I packed out a quarter elk and the held with mine last year and carried another quarter at the same time (yes, my nickname is mule now, thank you very much). Plus you can't beat their warranty. However, they are not cheap so sorry to not offer a cheaper option (but remember, you get what you pay for most of the time). My 2200 will last me a lifetime I'm sure and I no longer even look at other packs (although their newest version has a couple improvements I would enjoy).
