I couldn't agree with you more on your microphone selections. I do mostly feature now but did documentary for many years. I do find myself preferring the CMC6/CUT60/MK41 combo inside and outside whenever the situation is amenable. Most of the time there is far too much background noise and we use the CMIT5's outdoors. I also think the MK4 capsule is a great tool to have. It is an amazing sounding capsule with zero pick-up on the backside, so perfect in rooms with hard reflective surfaces IF you can get good placement relative to your source. Regarding wind screens, I love the B5D best for interiors and have used both Rycote and more recently Cinela wind protection rigs for any outside work very successfully for many years with all these mics. Regarding the 416, you are right to keep it. It's a great mic and you will never worry about having a perfect option on rainy, high humidity days, or when you need the most durability.
