What configuration of fabrics for my weight?

[Stormstaff]

And comfort?

Approximately 265-270 lbs.

I started thinking a double layer 1.9 just because but I think a double layer 1.1 will do and may be softer?

Let the suggestions begin.

Why not a 1.1 inner and a 1.9 outer DL hammock? Get the soft 1.1 inside and the strong 1.9 outside.

Can you use two different weights? Wouldn't they stretch differently?

The 1.1/1.9 combo is used in the WBBB multicam. I think you would be fine with the weights. Pit the 1.1 on the inner as it may stretch more.
