Own a Blacks Creek Canadian, love the pack, it is a little heavy but not bad. The only problem I have had is the main compartment zipper broke on me, and I have heard alot of people have had the same problem. When I called them they said send it out and they would fix it free of charge, other than shipping. Problem was it was in the middle of my hunt, and I needed a pack. It was going to take 3 weeks to get back. Bought a Badlands and still haven't gotten the Canadian fixed, just love the Badlands to much!
I have owned one of the older Jim Horn's signature Alaskan backpack and it has been a great pack! Knock on wood I have not had any issues with the zippers. I have hauled out quartered out blacktail deer and it has done well but the pack expands out so it can get a little top heavy.
