I don't like tents that completely surround me. I can't see outside, and getting out in a hurry is not easy. I can't gain any heat from a fire so I would need to carry extra bedding, and if I want to cook I have to go outside whatever the weather.
So I only use an oilcloth. I can use a reflector fire for heat and I can reach the fire to cook from my bedroll. I can roll out of bed fast if I need to, and can see everywhere but behind me. Sounds though I can hear very well.
