Even with limb saver limb dampening buttons the Z has slightly more felt vibration.

I feel the Cougar could benefit from some further tuning. The string serving is also very long, over 10 inches in length. The Nitro 1.5 cams have the general profile of the Hybrix 2 cams but are scaled down. The Cougar has an easier draw cycle with the smaller cams also. Not a huge amount but noticeable.
