3seasons I use my OES Cuben Standard. For winter I will use my new ZPacks Cuben Winter tarp. That said, if I go with my family of 5, I will use the winter tarp in 3season mode (doors folded open).
Recently received my winter tarp from HG as well. Cant wait to try it out.
Its funny, i had the same question myself about 3 season use.
I am trying to get my backpacking weight pretty low so a much smaller tarp is very tempting.
When i spoke with adam on the phone he said he can do a regular Hex tarp as well.
I have a 9 meter roll of blue CT1K.08 that is sitting in my basement that was going to be a MYOG tarp. But after seeing the craftsmanship of Adams' 4 season tarp i will probably end up sending the roll to him and have him make the 3 season tarp.
