I own both packs, the HH mainbeam and the BL 2200. I got a screaming deal on the BL and decided to pick it up. I am 6' 4" and have a 34" waist. The BL just doesn't fit me as well around the waist as the Mainbeam. In addition I don't like some of the pocket configurations on the BL either. However I do like the larger meat locker material but it really doesn't help you carry more. The scope sleeve is a plus too for the BL.
The HH has a ton of straps which I love. Last week we did a 3 day scouting trip on the Dutton. I was able to easily pack in a tent, pad, sleeping bag and food, scope and tripod, which was about 65lbs. (We didn't care to pack in light.) It felt great. I have used the HH to pack out 3/4 of my deer plus a tent and sleeping bag-just over 100lbs, and it did great.
I gave the BL to my dad and he has packed out a deer as well and it performed optimally.
As far as the different years. Mine is an '09 and my friend has a 2010. No difference other than the color of the "Hornhunter" enscryption on the pack. I know the BL there is a difference between the '08 and '09 model. I think. I can't remember what, but the one I bought was a 09 or '10 model and I liked it.
Just my opinion but I use the HH over the BL because it fits me better and I like the configuration of the pockets more, I wish I could take some things from each pack and create my own.
As for carrying a bow I would go with the HH. More straps and I think it secures it better. As for a gun- both do well but I like the BL more because it has the lower pouch that comes out and secures it better. I don't like the pouch on the HH that is attached to the bag.
You just need to go to a store and try the two on and see what fits you better. In all reality, you will not be disappointed with either. Or just order both of them and return the one you don't want??
Good luck.
