I'm a little biased, owning an 08 Firecat, but I think the Firecat TR2 would be my choice for hunting. I like the overall package of light weight, relatively small package, speed and accuracy my Firecat provides and mine doesn't have the benefits of the CAT-2 cams, new 5-layer limbs and improved limb cups the 2010 Firecat TR2 has. The Alien with Hybrix cams would be my other choice if you're willing to spend a little more money. These will give you more than adequate speeds at lower draw weight so they will be pleasant to shoot and still take game with authority.
