Reply to "Installing TVS Diodes across layout with distributed power - Overkill?"

You might want to consider using terminal blocks with the TVS connection on them and running the power wires to one side and the track connections to the other. 

You might also stretch the connections to every eight sections and see how it works out - that would cut your drops in half. If you start experiencing problems with voltage loss or other issues, you can always add more drops later.
