So I was on the Warbonnet website about to order me a double 1.1 BB when I saw this 1.0 option. I only weigh 150, but would like to use a pad until I can afford an under quilt hence the double layer. Would the 1.0 be a good choice for me? It'll be used down here in the South East where it's extremely humid most of the time. Saving a couple oz is always welcome!
