7 Bladed steel fan or flex fan,which do you prefer ?

How about a 5 blade mopar performance with a viscous clutch...efficient cooling with low drag at speed. That is what I'm shifting to shortly.

What does the rest of your engine compartment detailing look like? Stock type fan shroud? Other goodies custom detailing? Either of your choices would look good...depending on the rest of the details.

Good luck. I always seem to think too much on my project with questions like yours.
