My most recent ride has X.0 rear der. and x.9 triggers,which after a short while I have gotten very used to and comfortable with. my other bikes have basically either XT or XTR components. I am currently planning on building up a new bike and cant decide which drivetrain to go with, I am kind of leaning towards the sram. Id love to hear other peoples opinions and thoughts about them and which they prefer and why. thanks
