I had some time this afternoon to play with my new BB and Big Mamajamba Spinn tarp.
On the hammock:
I've switched out the stock webbing suspension for 7/64" Amsteel UCRs attached to tree straps with toggles. I tinkered with the hang a bit and think I got close to finding the sweet spot and getting rid of the left calf pressure. I hung the foot end about 8" above the head end and made sure I was not jamming down into the footbox. Re-watching the video on Brandon's website helped a ton with the little things. Everyone knows what a fine piece of equipment the blackbird is, so I won't gush any further.
The Big Mamajamba in spinn is simply amazing. I think the sil-nylon door kit for it weighs more than the tarp itself. I set it up on a single ridge line. I started out with the ridge line over the tarp, but I really didn't care for it hanging that way. It seemed that the tarp ridge line was almost over-tensioned (and I didn't have the tarp pulled out super taut). I moved the tarp over the single ridge line, and I thought it improved the set up immensely. The tarp is plenty long for the blackbird - it will take some blowing wind to get anything under the tarp wet.
There is a split ring hanging down from the ridge at each end of the tarp ridge. I'm really not sure what those rings are for. Are they for running a single ridge line through? Or do they serve a different purpose? (see picture below)
One of the tarp corners is missing the door attachment split ring and attachment. I contacted Brian about it and got a near immediate response. I'll be sending the tarp back to Colorado for a quick fix soon.
Here are some pics:
