IIIPRO Rotors : These have been discussed a lot. They are great. For the money I think they are unbeatable. I just did a 15k' day on them and they never warped or rubbed on my pads. They are relatively quiet and while not lightweight, they are weight competitive at a fraction of the cost. Really good.

I forgot there's one down side, the rotors are marked as resin pads only. Though I feel like they bite so well, I haven't had the need to use other pad material at least for road cycling. My riding consist of lots of climbing and descents as well.

I picked up these iiiPro disc rotors awhile back. They're a few grams heavier than my lightweight Onirii disc rotors I was using, but braking definitely has more bite. I liked them so much, I ordered a second set. Highly recommended!

The new’ish IIIPro floating center lock disc rotors are pretty good. I have them on 3 wheelsets and braking is solid. Just make sure to use a disc rotor truing tool if they’re not straight.
