I guess I could fiddle with something like
-S\

M/

-S
For especially long manifolds.
And I know manifolds are equivalent to tree like perfect balancers given time, but I like to see factories at 100% efficiency before I leave em and it's annoying to wait lol. Plus with "batch" like setups balancers are better than manifolds since you don't have a steady stream.
