As above...need a few pairs since my lightweight ones (ashima) just warp!
XT ice tech. Perhaps not the lightest but still...

Formula R1 1 piece rotors like the link above, really light and no weirdness in use.
Shameless plug, but have 1 for sale as well 🙂
Magura?
The formula ones can wear unevenly, but apart from that they're ace.
Never warped an ashima airotor mind, but I did find them vibratey and pulsey with some brakes.
Alligators are very light, I think around 76 grams for a 160mm one. I have a set on one of my bikes and they have been great and look good as well, oh, and available in nice colours.
Kcnc razor
Lot's of very light rotors on xcracer.com
Good prices as well.
The 1 piece formula R1 for me also. The rotors with the big holes can eat brakes and warp easily. Only 85gms on a 160mm
