Single shot racks - Parallel or Series

Here’s another discussion;

What is everyone’s preference when doing single shot racks? But I suppose as valid for anything, cakes etc..

I am a series guy as I like to know my continuity is good across every ematch, but also accept the argument that a damaged wire in a series circuit will stop everything on the chain firing.

Especially bad if you have 6 single shots on a single cue.. having 5 go would be better than none I.e parallel..

Intrigued as to what you all prefer to do.
