Love my KCY cables!! I've never had a problem with them being unbalanced.
it's a good choice and will work very well. I have this setup and the single cable is indeed very nice.
Do you think you would ever want to get a wider split with the mic capsules? If so another option is to get KC5 cables and chop them and terminate them in PFAs.
I have some KC5s but haven't chopped them. They're nice but keeping them from getting tangled is hard for me.
I tend to use CMC6 bodies most of the time now but the KCY is great and any time a small rig i can run in ORTF or DIN is called for it's the way to go.
I am going to be primarily running MK41s at first and don't expect to run a wider split but a very good point.
Me either, and Ive had  different Schoeps KCY's[still have 1], and I have an NBob KCY now too! Never had an issue with either being unbalanced, so no way I would ditch the KCY to go to KC5's
The single cable is sooo quick and convenient! Just icing on the cake IMO
But I do prefer the balanced connectors better, and was another reason why I wanted to sell my M10 stuff and get another 70d, so that I was DONE with 1/8" plugs for now
But everyone has different needs and expectations
