I've had a DIY hammock with bug net 11 ft long 68 inches wide for a couple of years now made out of Hexon 1.6. I enjoy it and find it to be pretty comfortable. I also have a 11' netless hammock made out of HyperD 1.6, which feels like it has just a little more give/stretch to the fabric which ok.

At 190lbs would 1.3 MTN XL likely be too stretchy? Does 1.7 MTN XL feel like it has significantly less stretch than Hexon 1.6?
