Wally Phillipswrote a review of SRAM XG-1295 X01 Eagle 12-Speed Cassette on May 31, 2017
Familiarity: I've used it several times
I have been using the SRAM Eagle X01 drivetrain on my new rig and I'm pretty enamored with it. The cassette is especially noticeable due to the HUGE 50 tooth ring at the biggest cog size. It really is a cheat code when getting to that gear range with a 30 tooth crank ring. The shifting has been crisp for the most part as under some poor pedal stroke weighting has caused some catching at times, but it is more pilot error than anything. Along with the cheating feeling of the 50 tooth ring, I'm finding it hard to pedal out of the highest gears as well at 10 teeth. If you have the means to, get on the Eagle drivetrain as soon as you can!
