What are the best 6 bolt rotors?

I am talking about trueness and quiet braking- Not lightest.

Long story short. My bike came with SRAM Guide ultimate brakes and rotors- I switched to XTR 9000 race brakes but kept the same SRAM rotors.
I am getting some howl late in rides after a lot of braking on long descents.

I've been very happy with the XT rotors on my Pivot Mach 429. 180 on the front, 160 on the rear, and no problems stopping my fat a$$ in any situation.

+1 for Shimano rotors.
I've been using them for several years now and they are trouble free.

Magura Storm SL? Competitively priced as well.

I'd look at the pads and other factors 1st.

I was using good pads- Resin XTR.

I ordered a set of RT86 6 bolt rotors. Will install them with fresh pads-

I'm running Formula R1R brakes with Sram Guide Rotors - Super Quiet.

Rich_W your brakes are from which year?

My old ones with the new xt rotors are always rubbing and I need to buy new ones, don't know if the newer R1R or XTR.

Thanks.
