I have 3 Pro Microtunes and 1 2000 and I don't feel there is a better sight on the market. I know I'm responsible for many on here purchasing a Viper and every single one of them is completely satisfied. There's a reason why I own 4. Back in 06 when I searched bows, prior to buying my first Bowtech, I bought the Viper Pro MT before I owned a bow. I researched all the best sights and the Viper sold me immediately.
