I have had the J107 pack for 3 years now and could not be happier. On a light pack in trip I was able to hike in 3 miles and take a deer. after boneing the deer, I was able to take the whole thing out at one time. I usually do the high hunts above salmon la sac and carry around 50 lbs which that pack will do with no problem. The spike camp duffle is perfect for putting you camp in and as soon as you get to where you are going to camp at you can unzip it and start hunting. this pack will handle as much as you can lift and works very well as a day pack. The very top of the pack can be taken off and used for a fanny pack. This comes in handy when stalking while bowhunting. I have taken this pack with me for the last 2 years in Idaho and it performed perfect. I have gotten my friends to buy this same pack and have not yet heard a complaint. I really cannot say anything bad about the j107. Hope that helps
