Quick access is not a big deal to me. If my rifle is strapped to my pack, it means I am on a mission to get up to my camp site or glassing spot. If I'm in a scenario where I might take a shot, I have my rifle in my hands or slung over my shoulder. To me, the scabbard like Eberlestock Dragonfly
promotes is added weight I dont need. I know that sounds ridiculous, but most veteran high country hunter knows that we are counting everything down to the ounce. Our first hunt we packed every cool piece of gear we own and might need. After one trip of packing around unneeded weight you are more interested in what you can leave at home, so adding extra weight to a pack for a feature that I (personally) dont think you need would cause me to not buy the pack. One of the guys I hunt with who is an average size guy owned a Dragonfly
for a couple years and always had a hard time pulling the gun out of the scabbard. Taller guys probably wouldnt have this issue.
I have never been a huge fan of having the gun on the side. Although it seems like it is a great solution, I dont like having extra weight on one side that causes the pack to feel lopsided. I try and pack my pack as evenly as possible so I notice uneven weight distribution.
To me, I prefer to have it on the back of the pack. I think the ideal set up is to combine what the Outdoorsman pack and Badlands pack do. I like the pouch that swings over the scope to protect it. I have tall turrets and I want the scope to be covered so they dont get bumped and the scoped doesnt get too beat up. But one of my biggest pet peeves when it comes to hunting packs, is when buttstock pouch extends below the bottom of the pack. I literally despise that about my current pack. When you sit down for a break, you have to take off your pack, or sit at an awkward angle. You cant just have a seat because the buttstock will always be hitting something. If you just sit on a log the weight is still on your back, defeating the point to your quick break. For me the best set up will be a pocket on the back that doesnt extend below the bottom of the pack, and has a pocket that will protect the scope. I always throw a gunsock over my rifle while going in to avoid getting all scratched up.
