I have used the old "freighter" frame, that Cabela's now calls the "Alaskan" frame, for about 25 years. I believe it has carried all or parts of 6 or 7 elk and several deer. It is still chugging along. The new ones have considerably better padding in both the shoulder straps and the belt, but the old one is lighter for hunting. I don't use a pack for meat, but would do so if I were to bone the animal. I have purchased two new ones for by boys, who have also used them for elk and deer.
I hang a day pack on my frame to carry my stuff. I have about 20' of nylon rope that I tie onto the frame to secure the meat, and that is plenty. I know a fellow that uses two bunge cords to do the same, but I prefer rope. It also makes a tolerable rest for long shots that can be set up in a couple of seconds, as I don't wear the belt when hunting.
Hope this helps.
