I am getting into elk hunting and have 2 trips planned this year. One in Idaho which will be a base camp type trip with an outfitter with return to camp each night. The AZ trip will be in unit 4B with day hunts from the truck. I am looking at the spike camp and late season packs. Both look to be good day packs. The main difference looks to be 1000 ci in capacity. My thinking is to go with the larger size and then use compressions traps to tighten the bag around the load. The other thing I thought about was getting the duplex frame and strapping a bag i already have to it. This way I can add a Nomad to it at a later time an use it for self hunts. I was just concerned that the duplex frame might be overkill for my 2 hunts this year. I guess it's just preference and cost. Want to make sure I am getting good gear and a good value that is comfortable and functional for the task. Looking for some advice from some of the experienced guys here. Thanks!
