Just my opinion but Iv run a para a lot. I'm a smaller guy so I fit in it. I like it not only for its versatility, but smaller size, sometimes finding a spot for these castles is tough.
Anyways, I had an annex and stove, IMO neither is worth it for a shelter this size, more pain than it's worth. My setup is a paratarp for run and gun trips or trips in warmer weather. the stove and annex become a pain in that now your stove, and wood are packed up right to the door, makes egress difficult. Yea it heats the shelter but you don't have the room, or the heat to really dry stuff. Unlike the larger shelters, not much pipe is inside the shelter, just the box, making it warm at the front and cool at the back. I think the stoves have much more value in a little bigger shelter, and in places your not constantly moving camp.
The shape of the kifaru tarps is awesome, and they will stand up to a lot when pitched tight to the ground, but experiment with other pitches, the beauty of the kifaru tarps is not only in their standard a frame setup. If your a bigger guy and plan on pitching the normal way every time, I'd suggest going bigger.
For what it's worth this year archery season I'll be running a paratarp with a borah bivy, light and compact, and easy to move daily if needed. I also have a cimmaron that will stay home.
