So I bought an RL cuben Lone Peak to test for winter backpacking. Unfortunately, by the time I ordered and received it, it was pretty much past winter, so I'll be using it next winter.
It's a nice shelter, setup is fairly easy, spread out the 'bottom' into a circle, start with closed doors and just stake around the bottom then insert the center pole. Very little restaking once it's up.
It accommodates a TiGoat or RL stove. Lots of room for one person, could easily fit two. Double zipper on the door. Taped seams.
On my cheapo kitchen scale:
Shelter: 20.5 oz with cuben stuff sack
13 Stakes in bag (it takes 12 to pitch, stakes include 4 groundhog-type stakes and 9 CF): 4.25 oz
CF Pole: 6.5 oz (can use trekking poles to save this weight)
Some pics:

lots of room at both ends of pad

lying on pad with one foot on top of the other, still not touching the inside of the shelter. Same room at head end.
.
with just one door open. See how much space is still in front of the pole. You can get in with the door fully open when it's raining and not get your stuff in back wet, unless it's coming down hard at an angle. Then just open the door half way and crouch in.

nice attention to detail
