The single wall Cirriform looks very much like a Tarptent Contrail would if done in cuben.
Weights that Yama lists don't include stakes so for 6-8 necessary stakes add 1.5 to 2 ounces to listed weight. (I prefer Tarptent's policy of listing weights including stakes and stuff sack (I think Yama did include stuff sack). Tarptent also includes good set of stakes in purchase price, which most vendors don't.)
With stakes it puts Cirriform SW up close to 21 ounces while Contrail is at 24 oz (but Contrail needs seam sealing). That's probably a 3 to 4 ounce real world difference in weight b/w Contrail and Cirriform.
I expect some might judge the weight savings with Cirriform SW to be worth double the cost of Contrail. Others not. I tend to think the comparison makes Contrail look even better than I thought it did.
I wonder what the Cirriform would look like in "storm pitch mode". With Contrail you can pitch with sides down to ground, don't see any pictures like that for Cirriform. There are actually quite a few different pitching options with Contrail, wonder whether cuben version has same flexibility.
