I had a Sky 5900 a few years back, I sold it when I took break from hunting. I no longer bow hunt and I am now looking for a pack for a rifle elk hunt next fall. We plan to ruck back to base camp most nights unless caught out on a herd or due to weather or day light. I was looking at the Col 4800 and wondering if it'll be enough pack for the task or if I should be looking to the 5900 once again? Any input would be much appreciated.
