Seems like it would be a really good ultralight combination. Weighing in right at 13oz for both in cuben. Using the .75 cuben for the tarp too. Could go even lighter if one opted for the .51oz cuben. Pretty great weather protection. Full bug protection. You can pitch the bug bivy independently. Tarp is no gimmicks. There's nothing to fail besides a seam or the material. No zippers or snaps etc.
One could contribute to lighten the tarp by switching out the 3mm guyline and linocs for a lighter option. Could potentially save up to half, maybe a full ounce.
Would anyone like to comment on this shelter idea. The only negative I've read about this shelter is well entertaining it in storm mode. All a frame tarps are similar though. I also read all though it can be pitched high, it's limited because the back end of the tarp is one piece so it cannot be pitched as flat as a grace tarp for example.
The .75 green cuben looks really good too
