I scoop and tamp, no air pocket as it's simply wasted space in my opinion. Just develop the "feel" for each layer's density and ... easy peezy, light and enjoy! But, keep in mind, each smoker is allowed make the process as simple or as complicated as they see fit. Some here enjoy meticulous attention to every detail. Others? We simply want to get to enjoying the smoke, rituals slow that process. It's what ever floats your boat!
