Presumed, there is merit in both arguements. The psk in it's minutae reflects bigger issues. Comfort may be a secondary issue in our experience and mindset. But add a child or senior citizen to the scenario. A favorite toy grabbed as you head for a tornado shelter: the upset english lady who just witnessed an aircrash and is talking about the blitz as you buy her tea. A tea bag may be wasted space in a PSK, but Im not going anywhere without my rucksack, teddy and Earl Grey ;o)
