I'm seeking feedback / advice / examples of city block designs, as I'm discovering that the four-large-poles-to-a-side block (90 tiles) that I've been using is way too small for my current project.

Let's assume that radar coverage and blueprint-from-space isn't an issue for now. Large poles span 30 tiles, substations span 18, and roboport logistics coverage spans 50 tiles. These competing increments are making it difficult for block-tiles to line up with each other in any sort of aesthetically-reasonable way. Any ideas?

Edit: I am specifically asking for suggestions on block size and configuration. I am specifically asking if anyone has a block size that works for them, from which I might draw my own inspiration. I have the specific desire to leave every block roboport-isolated from all other blocks. I've already worked for a few hours in a creative sandbox and I'm not happy with the results that I've had so far, hence my question here.
