I see a lot of folks are talking about using polyester or other fabrics that don't stretch in their gathered end hammock. I'm looking to do it in with a bridge hammock though. The bridge hammocks are a bit more finnicky about dimensions if you want a flat lay, and I would think that switching from Nylon to Polyester would create some fairly significant changes in performance.
Rolling it around in my head, it seems like it would actually give the bridge a much flatter lay if you weren't sinking in to the fabric in the middle where your weight is greatest. Has anybody tried this yet? Is there anything to be cautious of when designing a bridge with a fabric that doesn't stretch?
