Go with the 5500 no question in my opinion. You honestly can't tell the difference between the 5500 and 3500 when sucked down for day hunts, but you have the extra space for multi-day hunts when you want it. Ive been running the Exo 5500 for 4 years, and currently have the k2 frame version. They will be announcing something new soon for this year might be worth waiting on to see, but personally no way would i go with the 3500 if you plan on multi-day hunts. I see plenty of 3500 bag only for sale because people realize they want the 5500, but i never see the 5500 people looking for a 3500 haha. The exo hauls meat great, i do have the crib accessory if i'm just hauling a meat load, but you can also just use the actual 5500 bag for the same aspect.
