Mirroring a hole wizard feauture

Hi there,

When mirring features in SolidWorks, you can often save a hell of allot rebuild time by mirroring faces insted of the entire feature. But does anybody now if there's any drawback of this pratice regarding the Hole Wizard.

I have not tested i yet, but i'm concerned about SmartFastners, Hole Callout in drawings and Interfearence detection not being able to filter cosmetic threads.

Kindly share your experince with me.
