I got the very same email Ramblinrev. I ordered the supershelter and I went to a bigger snakeskin (4 instead of 3) to see if supershelter (without padding) will fit with a larger snake skin.
I bet it takes awhile for the hex to come in, but it was worth it for me. Now we'll see if this SS can deliver on "some" warmth. I'm sure it will need to be tweaked.
From what I understand the Hex comes ALONG with the original fly as well.
