Assuming money doesn't matter, what lightweight 0 degree sleeping bag would you buy and why?

For synthetic the Wiggys Ultima Thule is a -20 and lands at 5 lbs. Down bags such as the Western Mountaineering Kodiak and Antelope MF ,NorthFace Inferno will be lighter by almost half. Only thing with down is if it gets wet it looses it insulative properties and will take a year and a day to dry. Some guys take a bivy bag to go over it for protection but that kind of negates the light weight theory. Synthetic however if hung in the sun will have you back in the bag quickly. I have both, my down bag sleeps nicer but on Alaska or extremely remote trips in Canada the Wiggys gets the nod. If I will be in walking distance to the truck I take the down. Wiggys does offer lighter weight options as well for synthetic and western mountaineering has a down bag at 2.06 lbs called the “Versitile 10”.
