Excluding some of the more exotic bowl shapes, I actually found larger pipes to be more forgiving/easier to learn proper packing on when I re-started with pipes. With small/mid sized chambers, starting out I could over-compress trying to get in what felt like 'enough' tobacco for a good sit n' smoke. With a larger pipe, I had more confidence to simply small-pinch fill and tap level with one top off. Maybe it filled the pipe up, maybe I stopped 3/4....but by nature of greater capacity it gave me more confidence playing with my pack. In terms of smoking....you shouldn't need any big change in approach. Light n' go.
I tend to stick with chambers around 2 inches to this day.......I can keep most all size pipes smoking cool, but just like to be able to sit and smoke for a while if I'm going to take the time to prep a pipe.
