I have had pretty extensive experience with the Cave 2. My wife and I carried it up the entire length of the Appalachian Trail last summer.
What I liked was that it is very light for the room it provides. The pop up tie offs on the side of the tarp give you good internal space even if you have to pitch the tarp low. We pitched using 2 sets of trekking poles (1 for the front and back and 1 set for the pop ups). We would pitch the back end on the ground in rough weather and the front end about 5-10 inches off the ground. In nicer weather, we would pitch it even front to back with it a foot to 18 inches off the ground. The tarp is super solid in wind and is extremely dry. We did not have a single quality issue with the tarp in 6 straight months of use. There's plenty of room for 2 with lots of extra room for gear.
Really the only downside is that there are quite a few places to stake out. 12 to be exact. So - setting it up day after day was a little time consuming, but I never felt it was not worth it. When it's set up - it is bombproof.
All in all - I would highly recommend this quality piece of gear.
