As suggested already using manifolds with overflow smart splitters is the way I did it when I built a 10 heavy frame factory. The only place that hurt my brain was when I needed to split reinforced plate to 25 end points and there wasn't enough volume for a manifold to work so I needed balancers and a 5 way balancer broke my brain. Doc in YouTube had the answer which is split into two, then split those two into three and feed one of the six end points into a merger before the split into two. Then the five remaining end points get the same treatment and you end up with 25 end points for heavy plate.
Good luck!
I hear you, took me a long time to realize which ones are worth spending money on.
Shoes, toilet paper, tires, underwear, etc!
