How to use Deus/ZPU Anti-Recon in a stack?

Hi, I was wondering, with modules such as Deus and the new Anti-Recon, if you were planning to run more than one Custom (or voice-embedded major title with one of these modules added), would it be optimal to include one or both of these modules in each of them (the custom/voice embedded Sub)?

Or would running them in one Custom be enough, since the affects would carry across to any other Customs/Subs you were listening to?

When you stack customs, the modules in each will blend in across the board.
You don’t have to have Deus in every custom for it to benefit all the scripting.
