Mine arrived yesterday (1.7DL) and I had a spare few minutes today to string it up. Wish I had more time this weekend to give it more of a trial run.
I really like the extra mesh. It makes a big difference compared to my WBBB in visibility. I didn't really feel "closed in" with my WBBB, but I definitely like the openness of the XLC.
The extra length felt nice and I was able to be nice and flat (I'm 5'10"). It felt a good, I actually fell asleep for a few minutes. It was only about 50 degrees out and I woke up with a little CBS. I didn't get a chance to test out my quilts. I'm wondering it I will have to add an extension to come sate for the longer length. I'll have to check that out later.
FYI on those waiting for theirs and the shipping time: I ordered mine on day one (actually, I ordered it before their webpage was fully updated).
Now, I'm a newbie with only about a dozen nights is a hammock, so take my quick review with a grain of salt!
