Hi,
Great advice so far, I'm sure there is more on this topic so please add more if You have.
I checked Brodak control line wire (cable) and they have these wire diameter to choose from.
They do not have any weight listed.
What diameter do You recommend?

I have noticed some cables (not Brodak) for pull-pull are coated - what advantage might that be for our purpuse?
Just some extra weight in our case? If stainless wire, like Brodaks, it will be no corrosion/rust for our usage so need for coating because of that.
