I agree with you, down bags are still my first choice but you still do need to take some precautions like you said above. Syn bags (Primaloft One only) can also be a good choice under the right conditions but they are no match compared to good down bags. Both of my bags are breathable and I never had major issues with condensation/wetness, even when I bivvied on snow. I am glad I invested the money. I think I have had my MH Banshee for at least 10-12 years and is still as good as they day I bought it.
