Looking for better rotors
After one trip down the Bighorns my rotors warped, pulsing pretty bad, seemed the right front wheel was very hot compared to the rest and had a heavier dust buildup on the rim. Had the Ford dealer in ...

Agree with others who have said that it is most likely your driving style...
The Stop Tech article is very good, but do disagree on one thing...I've measured
run out on many rotors. Meaning they were warped.
Think your rotors were NOT warped, but high spotted with baked on friction material
Drilled rotors are pure track stuff and/or for folks who have the money to replace
them often
Cast in holes are okay (Porsche is one), but $$$$$
Slotted is a good thing. Why does the 'good' pads have a slot either cut or
molded into them?
Same reason slotted rotors are better.
The comment of reduced mass is correct...for drilled/cast 'holes' in rotors.
Depending on how they manage the placement, dia and numbers of holes...has come
lose approx 30% or more mass from those holes
Also, holes only work well for high RPMs. Meaning for those who have ~24" dia
tire OD's or driving over 100 MPH, sustained with our truck tire's OD
Slots (pad and/or rotors) allow a gas escape routing. Otherwise the out gas
pressure is high enough to float the pads off the cast iron...AKA Fade or reduced
braking
The mentioned braking HARD, then letting the cool is the best advice on HOW2
brake on inclines.
