pack light and freeze at night. Or you can haul the tent if it makes you comfortable. Don't get wrapped around the axle over Kg or so... it's not gonna make a huge difference. If you prefer a spacious tent to a bivy and the stars: go for it. I prefer a bivy. But then again, I've lived out of a bivy for months on end and learned to love it. It's all in what makes your tour enjoyable...
