I've used the Golite Hex 3, now called Shangri-La 3 for I think 2 years now, and it's my definite favorite among four generically similar shelters I own. I have used it for....at least 20 nights.

That said, I've used it only a few times in especially heavy rain. Several of the seams leak. When going solo, these spots are easily avoided. When sharing space, it's not so easy.

The tent has eleven seams. That's a lot. Each one is probably six feet long or more. I had the impression that the manufacturer said it isn't necessary to seal them. Whatever. They need to be sealed for other than light showers.

What a pain.

I bet the Black Diamond Megamid has far fewer seams, and is a larger and lighter tent. That said, the Hex has a trimmer cut (to my eye) than Megamid, and in theory, slightly greater wind resistance due to shape.
