Well I realize this is a long shot but I thought I'd throw the idea out there in case someone is in need of extra cash. I'll trade my Zpacks Hexamid Solo Cuben Fiber tent with extended beak, plus the Zpacks Cuben groundsheet plus the Zpacks Carbon fiber pole + cash for your Six Moon Designs Skyscape X. Your weight (without the pole) would actually decrease slightly (according to the manufacturer's specs) from 15 ounces for the Skyscape X down to 13.4 ounces. And, your wallet would fatten by an amount to be negotiated.
I purchased the Hexamid from another BPL member from the Swap. It is in nearly new conditions but does have a very small hole in the netting where the previous owner poked the hiking pole. The tent is factory seam sealed.
Here are the details on the Hexamid from their web site.
Hexamid Solo tent with extended beak. 10.7 ounces - $360
zpacks Cuben groundsheed - 2.7 oz, $95
48" carbon fiber tent pole - 1.5 oz $22
(full retail on the set $477)
PM me if interested.
