I agree with Blanchard on the gun bearer. It’s quick to deploy and re-sling and gives me two hands for using Trekking poles, climbing, glassing, or accessing gear I have in my hip or chest pouches. Depending on how you hunt this may not be important and the scabbard might fit your style better.
I think pouches need to be purpose driven. You don’t get purpose with some manufacturers, you get 6x9, 10x10, etc. otherwise a ziplock bag will do just fine.
