Another vote for the MR Pop Up 28. Mine has been used for 3 years, day hunting and hauling boned out NE whitetails and Wyoming antelope and Muleys. Fantastic little pack. If you need something a bit larger, for more heavy weather late season clothes, or couple/three nights bivy, the Sawtooth 45 on the Guide Light MT frame is another great option.
As far as the game bags, I've been using the same Caribou Muley bags for 4 years now and they're still good as new. I expect they'll last at least 10 years or more. I throw them in the machine with a cap full of bleach to disinfect, air dry, and they're ready to go again.
