Guide R's. They're fine. The smarter move here is to pull this thing apart this winter and fix what needs fixin'.

How long should rotors last? I'm trying to remember how long I've had my Hope floating rotors for now but its surely been at least 4 years now. Do you guys measure rotors and replace before they're cooked? or just wait till they're obviously glazed/bent/warped? Or just time based replacement?

What 200mm rotors (that fit Dominions ~max 2.0mm) are good?

I've never worn any down to the point where they fail the thickness measurement, but I've tossed plenty due to being too bent or too contaminated.

I used SRAM HS2 and Galfer Sharks when I had Dominions. HS2s work well but will probably need some time on the stand to true them at first. Sharks are super expensive but come straight-er, hold true longer, and have more bite. I haven't tried Galfer Waves yet, but NSMB just reviewed them and they sound comparable to the HS2, maybe a tad better.

Ive been running TRP TR33 rotors all year and they've been great.

I had Trick Stuff HD rotors that are just a hair over 2mm, but couldn't get them to stop rubbing. They'd be great and silent, but one or two hard braking moments and it's be back to the constant tsk tsk tsk tsk tsk

I replace my rotors when they bent or really turn black and purple. Not often to be honest.

The Galfer shark rotors are bloody expensive here - $150 each.

I wanted to try the Lewis rotors (pretty cheap here) but at 2.3mm they won't fit Dominions.

I put a set of the Chinsesium ZTTO 2.3mm rotors on my downhill bike and I've been impressed. I've ran them with Shiguras and XT and they've surprised me. It took a little to get them straight out of the box but since then they've been fine.

I use Chinesium Centrlines at $20 for 2 x 203mm and replace them every 6 months or so. With my Cooma Ultras.
Bulk runs at Maydena as you know is as hard on brakes as anywhere.
