Wagner rotors and severe duty pads?

Most the time when people think they have warped rotors, it's actually the fault of not bedding in the new pads correctly. During bedding, there is a transfer of the pad material to the rotor. If the bedding wasn't done correctly, you will get areas of the disc that got it transferred and other areas that didn't. You get the pulsing brake pedal that feels like a warped rotor. That is also why it's so important to turn or use new rotors.

Your reasoning is a bit faulty, it seems to me. You say that the bedding in of new pads can cause pulsing if not done correctly. But that could happen with new or turned rotors, so used rotors should have little effect if the pads are bedded in correctly. If you feel that your brakes work better with all new parts, by all means go for it. Just don't advise others that it's necessary.

Pulsing brakes are a reason to change rotors. I've changed umpteen brake pads over the years and have never had a pulsing brake afterward. And I never change rotors without a reason.

True statements. Too many on here take "their" method as an absolute, when like all things in life, there are very few absolutes. Some people just don't like to have to analyze every situation separately and apply a one size fits all solution every time, be it overly conservative or a less than complete solution.

In a long line of vehicles sold at well over 100kmi, I've actually just put the first new set of rotors on a vehicle since probably 1995. Why? It's the first vehicle that has needed them.

Fwiw, for you mandatory rotor turners or changers, try just scuffing the rotors well the next time if they aren't pulsing or worn out. It works.
I do the same on my snowmachine clutches. Every year, scuff the sheaves real well. It brings back that loss of performance or friction and while it seems "rougher" on the belt, it actually preserves belt life through less slippage.
