WTB 20 Degree or Warmer Down Sleeping Bag

I am looking to buy a sleeping bag that weighs less than 3 pounds and is rated at 20 degree or warmer. I am only interested in down bags. To make this search all the more complicated, I am 5'9' so the bag usually has to be a long in women's or a men's bG. Let me know what you have! I am particularly interested in Feathered Friends, Western Mountaineering the Katabatic Palisdale or the REI Magma 17 but I open to other options.
