There's only one choice as far as I'm concerned. I specifically researched sights before I bought a bow to put it on and when it came down to micro adjustability, .019 pins plus an option for .029 and .010 pins, aircraft aluminum constuction, percision machining and just plain looks which includes a harmonic dampener...the Viper Predator Pro Microtune (PRO-MT) from Viper Archery Products.
