retrotramp,

Your spinnaker 2 person tent already exists. It's called the Squall Classic--designed by Henry and sold by Gossamer Gear in a partnership together--and it fits two people. This spinnaker tent weighs slightly less than 25 ounces with stakes and with the use of one trekking pole. This has been my favorite tent since I bought it a year or so ago, but I don't need the extra space for solo hiking. I look forward to trying The One out as soon as I can get my hands on one. I look forward to losing another 6 ounces or so off my base pack weight.
