Can anyone speak to the TTTG SB "Original" double vs single? I'm 6' 180lbs but I'm looking for the flatest (side sleeper) most comfortable hang. I realize the single 1.9 is plenty strong, but does it get just as flat as the double? Also, can anyone speak to the taffeta liner? Is this noticeably softer?

According to the website, 1.1dbl vs 1.9dbl is only a 2oz difference.... so at this point it's more about the single vs double layer for me.

Any input would be great.
