Iv put a lot of nights in under a paratarp. It’s not a bad option for decent weather, and if your not too big of a guy. At one point I had an annex and a stove, but IMO it’s just too small of a shelter to use it with an annex and stove in the traditional pitch. I almost never pitch it right to the ground. If a tight to the ground pitch, and an annex is what you want I’d look bigger. I use mine with a bivy underneath, when weather gets bad I prop my half zlite foam pad up against the pole like a mini annex.
Not my first choice for a shelter if I’m expecting weather. But certain times and places it’s a pretty slick setup. A bivy makes it a great run and gun shelter: it’s very light and takes up no space at all.
I’d go with the para. I wouldn’t want any smaller and I’m 5’6 150lbs.
Any other questions let me know: I have a lot of nights under the paratarp. Most good, some bad, and a hand full of wet nights.
