A double layer 1.9 would hold you just fine. (Joann's ripstop is 1.9, and 50% off coupons are commonplace.) I believe Papa Smurf did some testing and found the polyester tablecloth would hold more than your weight. From a suspension view, 7/64ths amsteel or strap suspension is no problem as long as you follow the 30 degree rule of thumb.
The only other first consideration is length... unless you for are trying to go lightweight... i'm just under 6 feet tall, and I make my hammocks 10'6" -11' long (before hemming)
