Looked at one of these today. I had gone with the expectation of making my final decision between TN Voyager and Solar 2, but was quite taken by this MSR and its many neat touches.
One concern that I have with it is that, on the sample erected in the showroom, the fly didn't come anywhere near the ground - not within 6" in places. So I fiddled around with it, as is my wont, adjusting poles in eyelets, changing tensions but couldn't reduce the gap. The groundsheet comes well up the sidewalls presumably to compensate for this "gap". Looking at the MSR website, the illustrations there seem to show that the fly is more snug ground than the example I saw.
