siltarp above tent in real soakers keeps tent drier, even a tent with a rainfly, and gives a person a dry zone around a tent. very nice, and siltarps are negligible in weight penalty for trad touring.

shake tent while rolling up usually gets tent drier, even in a rainstorm.

hang guyline above tent, move tent fly to guyline, shake and pack tent in dry zone under fly. shake and roll fly separate.

have tent like suggested above that sets up independent of the rainfly and can be broken down underneath. setting up in a pavilion is always very, very civilized.
