Another consideration with the DD webbing might be how much moisture it holds/wicks?
I got concerned about this after my first couple of test hangs in the back garden so I changed mine: first of all for some webbing off an old ratchet strap (forgetting it had been wrapped round an outboard engine for a couple of years and exposed to UV - first ever night camping in the hammock that webbing ripped with a nice tearing noise and dumped me on my **se in the wee small hours.
Second change was more recently to whoopie slings and I'm delighted with that. Easily adjustable, no stretch.
But back to the point - the DD webbing seems very porous or spongy? I can't say for sure that it is, just that it seems that way. Using the carabiner mod will stop that, but you'll still have wet and heavy webbing to store?
