Tips for routing shower drain

[Marbu]

Hello!

Initially, I planned to run the drainage from the floor drain according to the red marking, but this option results in a very large hole in the joist (space for the coupling), and the hole isn't centered in the beam either.

Is it better to run it according to the green marking? Smaller hole and centered in the beam? But a bit longer and more bends.
I will only build with 45 bends.

From a construction standpoint, green routing must be preferred. It's only shower water that will flow there. Are they 50 mm pipes?

75 pipe, it can also be routed more tightly than I sketched, I saw now after a bit more testing. This solution will probably be chosen.
