For years, I've been packing my tent just like the manufacturers did - fold, pack poles in the center, and roll to fit in the tent bag. I just downloaded the instructions for the Helen Twowheels Super Packing System, which tell you to put the poles in the bag, then the fly, and finally stuff in the tent. According to the instructions, it's better for the tent and faster. I sure believe the faster part, not to mention being easier on old knees!
Do your fold and roll, or just stuff it?
