RE: 2008 Martin Cheetah Bow?
It's good bow, with most of the attributes of today's parallel limbs. Quiet with little hand shock. The MPro cam is one of the easier drawing cams today which makes it feel very smooth. It's too short for my tastes, but to each his own. Personally I'd spend more money and get the new MOAB.
By the way, MSRP on the bow is $350. I've seen most going OTC for $329. For $400 you get it's slightly bigger brother, the Bengal, and a MOAB should be about $475.
