Good rotors in 2022?

Both me and my girlfriend are running the Magura Storm HC 203mm rotors, and both of our brakes make the same whistling sound on longer downhills... there seems to be some kind of resonance in the hole-pattern.
It's not super-annoying, but more silent would be nicer...

How were they packaged ?

Being magura. I'd just be happy they weren't constructed from plastic.
They were in the original Magura packaging, and stored without any weight over them here after receiving them. Maybe it's because they package them in a thin sleeve with the small plastic packaging containing the bolts getting pressed in there. Never had an issue with Shimano rotors. Oh well, some truing will ensue at some point if I ever need them!

Can we do a RM brake rotor?
I asked intend if he'd do a high carbon rotor and he said no because people won't be able to deal with rusty bike parts.
I'll have a rusty rotor if it provides increased friction and conductivity.
I would buy up a batch of those. I SWEAR by the high-carbon tool steel solid rotor on the front of my 450. Aside from the friction benefit, it seems to be tougher than hell for rock impacts too.

Yes, it will rust. No, I don't care.

I was hinting at them being bent in transit. Not by you . They travelled a long way to get to you. No?

Cornelius from Intend said the reason that he stopped offering his rotors was that they came warped/bend from the manufacturer and he had no resources to check and align all of them upon receival. So maybe not bend during transit but coming that way from Magura?

When did he stop selling them?
I got 203mm ones from him and they seem true, I really like them but I need to put 0.5mm washers under my front caliper(MT7) so the pad doesn't contact the disc's spoke, gets a bit jerky at low speed and makes a weird noise.

A while ago. I PM'd him on the German message board MTB-news.de to inquire why they were taken off the homepage, so this is what he answered. He keeps the leftovers from production for himself.

Maybe that's why the 180mm rotors weren't replenishing, I ordered mine in July.

The TRP-42, 2.3mm rotors aren't anything that I'd recommend. Despite being a 2 piece, they're warped pretty fuckin bad right out of the packaging. Spinning them with the calipers mounted, they hit on both sides. Also, their measurements are weird. They say 203mm, but cause of that "wave" they have the brake pads (code and V4's) don't hit it right. Even trying no spacers and multiple thickness spacers. They just don't seem right.
