Yeah... That's what bias means...

Okay, I see what you meant. I didn't realize that the fabric for the
hammock bed is oriented such that it is on a diagonal to the fabric
weave, or like you said, on a bias of the cloth. Thanks for pointing
that out, that does mean that what I stated was not correct. I now
see that the side pullouts are positioned to 'compliment' the asym
nature of the hammock rather than 'causing' the asym nature.
- Shane,Many thanks for your explanation of the bias cut for asym hammock design. I wasn't aware of this and it adds an important new dimension to my attempts using my test hammock. See post on my variation on this idea.I like the HH too, but I want to make a light, efficient open hammock, without net or other HH features that is as comfortable.Best, Todd in Tarzana.

It was the Hennessy UtraLight Backpacker Asym, which was the first
asym model that came out and the only asym model available at the
time I purchased it.
I believe we had discussions previously where we disagreed on a
particular point and someone wisely pointed out that the hammock you
were using was larger that the one I had and that might be why we saw
details differently. I believe you use the Hennessy Explorer Deluxe
A-Sym, which is a bit larger than the one I used. That might again
explain some of the different opinions as well as the fact that I
used the side pullouts with mine and you apparently do not. But then
again, it is also possible that we see the same thing but judge it
differently... such is life.
- On test hammocks, Risk has a great idea there. Thanks, Risk.Try this variation so you can try different gathers and bias ideas:Instead of an end knot, pass the gathered material on each end through a Home Depot welded steel ring, about 2" in diameter and 3/16" thick. Secure the material to itself with a split piece of black rubber hose and a standard stainless steel worm-gear hose clamp. Buy the hose, about 1 and 1/2 inch in diameter from the same store. You can buy 1 foot off the roll, cut this into about 2 1/2" segments and split them along oneside with a knife. Cut out 1/8" or so if the hose doesn't close tightly enough around the folded hammock end.This allows you to clamp and unclamp in minutes.WARNING!!! If this is not done right the material can slip through and you'll hit the ground! This happened to me the first time I tried it.Make sure the clamp is very tight, don't hang the hammock very high, and put a lounge chair pad on the ground underneath just in case.Better would be to sew a safety margin on the end of the material so it can't slip throught the clamp even if it slips. This is for design testing only!I learned a huge amount from doing different folding and rolling schemes, including off-axis rolls and folds. There's nothing like lying in a hammock real time to figure out what's going on, and this method makes it possible. Small changes have large, non-obvious results.If this is not clear, speak up and I'll post pictures.Best, Todd in Tarzana.
- So, can you tell us what you learned? Especially on the off axis

I used the older non-asym ultralight backpacker on the trail for about
a month, too.
The big difference to me was that when I rolled over in the asym I
need to switch diagonals. I almost always sleep with a pad in the
so switching diagonals is a pain. It didn't feel roomier to me. (But
so I had plenty of room to start with.)

parallelogram, like so: http://tinyurl.com/62zmc
I kept the bias of the cloth aligned with the support points (i.e.
centerline of the hammock), since you don't want any stretch in that
dimension. I got a moderate asym feel with a 3" cut on each side.
I'd be tempted to go to about 6" for the next try.
