Do Mini Roots Blower/Superchargers have gear whine like 6-71/8-71's?

I am trying to decide between using a Weiand Pro-Street 177cid blower and a ATI Procharger on my new 454 for my '70 Elky. I think the deciding factor might be the gear whine, which I want. I don't think the ATI Procharger will have any whine at all (or does it?). Has anyone used the ATI Procharger? Thank you for your time.
