Not a power supply question, but rather a Power Injection T one.

To the best of my current understanding, If I power inject and use a different power supply that the first, I should use a T that doesn't continue the V+ through the T.

If I am power injecting with the same power supply, I can use a T that does continue the V+ through it and I can also back feed power in the opposite direction to the data signal flow. My question is then, If I inject multiple times like this in to a prop, should each injection lead have the same length, so that the risk of overloading the ground wire is next to nothing ?

I understand, that If using multiple power supplies, connecting the grouds together at the power supplies can lead too overloading the ground the wires.

I'm trying to work out how many of each type of T to buy. But thinking I should just buy heaps of each. How many would be recommended for 5K pixels ?

Cheers
