Cant beat that offer. On a side note, Aron are you going to do a review on some of those packs or if I have questions is it better to send you a p.m/call/email?
I will add that I bought a Kifaru BT2 this spring and have been extremely happy with it and continue to like it more with each use, especially after packing out a few elk. All of the packs you are looking at are great packs, so just think which one would fit your needs/wants best.
