There is some confusion and it's my fault for hijaking this thread and changing the subject. My bivy is a bugnet bivy from MLD, not the type of bivy to which the OP refers.
The bugnet bivy is plenty big and became twisted because I did not adequately hang the net off my face or stake it down.
I agree that you shouldn't have one approach to sheltering. I have relied on shelters, used a free-standing tent, used a tarp tent, attempted hammocking (consistently use it on day trips to the local parks) and wanted to try something new. My ultimate goal is to cowboy camp but one step at a time.
