Similar situation, under 70kg. In the last 2 years, and knowing because of age that this will be my last round of outdoor gear purchases, I've gone through the process of replacing all the major items in my kit. The target was to halve the weight of everything (including the rifle). It's do-able for almost all items without sacrificing functionality. As for the additional weight of meat for the walk out, it certainly helps that the reds in the southern Ruahines are on the small side. Typical weight for boned back legs and steaks rarely tops 15kg. I keep to under 30kg for the walk out. The end result is that I'm still going in regularly, while every one of my hunting mates from our twenties have given it away.
