Thanks for the feedback, guys.
I called my NAPA dealer and their brakes are in fact made by Raybestos. For my application they offer a premium pad which is semi metallic and a super duty pad which is also semi metallic but uses a harder material which will cause more wear on my rotors, in my opinion. Their super duty is recommended more for commercial applications where heavy loads are regularly transported.
I didn't get a chance to call Ford and find out what came originally on the truck, though I suspect they were semi met's.
I know there is a variety of grades of material used for pads. Unfortunately, I don't know the pros/cons to each.
Ceramic are supposed to be cleaner and dissipate heat better, but how long do they last under hard braking?
The premium variety of semi metallics are supposed to be made of harder material, but does that mean shorter life for my rotors and increased chance of squealing?
Right now I'm just doing my front pads, but I plan on using same brand for my shoes when it's their turn. So far it looks like I'm going with semi metallic Raybestos.
