Warbonnet Blackbird XLC Material Differences

I recently purchased the Warbonnet Blackbird XLC SingleLayer 40D, and I have found the hammock to be too stretchy and not that comfortable.

I tried out a friends hammock that was a thicker 70D ripstop and found it to be a little bit firmer but much more comfortable.

So I’m looking to trade my hammock for a different version, but I’m not very sure on the material I should get.

I’ve heard that the Dreamtex that Warbonnet makes their hammocks out of is super good, but it’s unclear if their 70D heavyweight hammock is made out of Dreamtex or not.

But also, how firm are the dual layer hammocks? Is it equivalent? And do the dual layers ever get finicky to use?
