HI, I think this is my safe true opinion DESPITE the fact that I have a badger for sale!
I would never want a wp/b on a sleeping bag. If I think it is going to get wet, I avoid that or have a cover. Microfiber is lighter, more compact, durable, breathable comfortable. The Badger is the best bag I have ever had and I have had everything from Marmot Lithium, Helium eq, several ff, Santa Cruz Down Works, Mountainsmith Vision, Propel, Beeline. The Badger is the most comfortable, warmest, best made bag I have used. I am only 160 and I still love that extra room. I think it is close to as warm as the old Lithium,
