Excellent choice. There are lots of them out there are it is easy to get parts and service. Hasselblad is a real system so you can expand later if you want to. Zeiss glass is very good and nothing beats a good piece of glass.

In a word, YES.

You are right the Hasselblad is more robust.

Ever take photographs in cold weather? Batteries get weak and fail. A V series Hasselblad is all mechanical. The only part that could give problems is the light meter in my PME finder, and that has never happened to me even in snow storms. But if it did I would estimate the settings and bracket if possible. With electronics there is always a possibility of failure in cold weather.
