I’ve had a few eberlestock packs but I keep using the main frame and started using their vapor 2500 bag on it. The frame is great for packing out heavy loads with the load shelf. Maybe consider the kifaru universal gun bearer as a lighter option than the eberle pouch. Had a team elk used it once sold it. Maybe it didn’t fit me well enough but it was heavy and I didn’t like the barrel sticking below my pack if I used the built in pocket. Still have a transformer but probably won’t use it. But I Keep using the main frame with bat wings or vapor series bags. Just me but I don’t like putting meat in nylon bags. So I strap my meat bags to the frame with whatever bags on the outside or sides. When you do your first pack out you can drop the bags and just go back with the frame and water to recover the remaining meat.
