did you follow any specific plans for your DIY Supertarp? I did my first DIY project and was a quilt and was hoping to try and supertarp/annex or equivalent this year but trying to keep weight in mind and sounds line yours is pretty lightweight.
Interesting design. I would prefer the shorter pole inside. Wouldn't require too much more fabric, would make it easier to pitch, and you'd get a bit more square footage to boot.
Im afraid your weight estimate is pretty conservative but i have been wrong many times before. 7 yards of 1.1 oz material will actually weigh. 14.14 oz. The 1.1 oz is per square yard. 7 yards of fabric is 14 square yards. Not sure if you worked that into your math or not. Obviously you wont use all of the 7 yards. My diy supertarp with zippered annex and 10 6" aluminum stakes weighs 2 lbs 5 ozs. The 10 stakes weigh 4 ozs total. I used either 1.1 or 1.3 fabric. Can't remember. I assume you will use your trekking poles to pitch, but if not you will have some extra weight for poles. I use my trekking poles so i do not include pole weight in the shelter weight.
Looks like you are on the path to a good shelter though. Enjoy the journey. Thanks for sharing it with us.
