I'm about to build my biggest factory yet and for it I would to try the for my new concept of a main bus.
Unlike so many others I like to have copper and iron on the same belt when I split off, but I find it quite hard to make a four belt wide mixer.
You can see my best attempt below.
Does anyone have any ideas for improvements or perhaps a simpler way of doing it without losing speed or compression?
Space it not an issue.

*Edit
As it so often happens as soon as I ask for help I come up with something better.
I however still think some can be improved
