I'm currently running a Crankbros Highline 3 150mm with a Wolftooth remote. Got it from Backcountry for $160. The Highline was really simple to install and so far seems to work well although doesn't feel as smooth going up or down as the cheap BrandX's I had on my other bikes. I like the Wolftooth remote, I like the textured paddle and the amount of adjustability. I have the ISpec II mount that gets clamped under the brake lever. The clamp allows for rotational adjustment on the handle bar and also is able to be slid in or out 1/2" by loosening the bearing bolt on the lever.
