I'm getting ready to pull the trigger on a double layer XLC. What do I need to consider when selecting the fabric weight (1.1 vs. 1.7)? I weigh 190-200 lbs, so the 1.1 would definitely hold me. My understanding is the 1.1, besides being a tad lighter, is softer (smoother) and has a bit more give. Does it stretch to the point where it leaves permanent stretch marks, or does it spring back? Does the smoothness of the 1.1 cause you to stick to it in humid weather, or does it remain slick? Can skeeters bite through 2 layers of 1.1? This is my first hammock so I'm not really familiar with the advantages and disadvantages of the various fabric weights.
Also, are most folks ordering their XLCs with the optional top cover?
