Valve Springs for Voodoo Engine options

[spartan]

These are two options available for the 5.2 engine. The Ferrea is 10X compared to Ford Performance option. Anyone have any feedback?

I have no experience with newer dual springs, but in general, I am 'sold' on the better damping properties of beehives in general. I believe that is the main reason why there aren't many offerings to 'improve' over OEM parts since the early modulars (2V 4.6L) and even those offered were beehive shaped.

A couple of videos for those that have not seen the operational differences:

Wow. $2k for a set of springs.

Did I read this right?
