RE: The 07 Martin Pantera
If you are told the Martins are noisy then you may be in for a pleasant surprise. I own a Pantera, but mine was custom built with Nitrous X cams on it. Not as smooth or easy to draw as the MPro cam, but quite a bit faster. The biggest difference between the Bengal and the Pantera is that the Pantera has an approximate A2A of 35", whereas the Bengal is 32". Either way, a smoother cam you're not likely to find.
And these bows perform very favorably against bows from other makers costing upwards of $300 more.
