I had to read it a couple times But I think I am tracking now, took me a minute to wrap my head around what you were saying. So instead of the coil of hose I have now I should do something akin to the below as opposed to a single hose line. I can see now how the system you describe would be much less restrictive in terms of flow, a bit more labor intensive to build but it does make a lot more sense.

The verticals being the manifolds, and the horizontals are the smaller diameter hose.

Thank you very much for pointing me in a better direction.
