I'm also 5'9" and my first custom hammock was (and still is my most often used hammock) a DH Darien 10-footer (1.7 Robic) with Smurf-recommended width of 64", and I find it supremely comfortable, somewhat more so than most 11-footers I have tried. Love it so much I got another made with 1.2 Robic. I have noticed less (practically zero!) tendency for calf ridge with the Dariens compared to most 11-footers (all 58" width... maybe wider would be better) that I've slept in.
