I bought a Cheetah in 07, because I wanted to hunt turkey. It was my first compound bow, I hadn't shot a bow for years and didn't know if I could get into it. I have shot turkey, deer, elk, moose, pigs and bunch of small game with it. I've been pretty rough with it. just carrying it around in my truck in a soft case. I even changed cams out for my new wife before she got her Passion. It has never failed me and is quite accurate out to 50 yds.
This year my wife bought me a Z7. Now, I love my Z7. It is quieter and smoother and looks really cool. But I still carry the Cheetah in my truck all the time. I don't think you can go wrong with the Cheetah, especially for the price and the service the people down at Martin offer.
