I have one of the Man Kung, it is the PSE viper. In fact they make the Viper for PSE and other bows for some companies. I have to say I was not expecting much, I got it and was going to use it as a back up. But I was surprised it shoots very well, once dialed in was 3 inch groupings at 40 yards and still burying arrows deep in the target. Dont get me wrong Ten Point and the other highend brands are great but I would put the Man Kung MK250 up against any bow in the $200 to $400 dollar price range. I now shoot it on a regular basis. I do use 20 inch carbon bolts though the 17 inch ones suck.
