Mathews Z7 Extreme
Personal Commentary by Jon Silks about the Mathews Z7 Extreme:
Mathews is particularly skillful at producing top-notch rigs year after year. The Z7 Xtreme is an excellent performer, never leaving the top four in any of the subjective or composite categories. Only in speed did it dip to number 5. A short axle-to-axle length makes the Z7 Xtreme very maneuverable while the single cam rolls through the draw cycle with little effort. The test bow demonstrated a remarkably quiet shot, little kick and virtually no vibration. The grip was good other than a small ridge on the upper back portion. Surprisingly stable for such a short bow.

Using the Above Table: Kinetic Energy: (in foot-pounds)
This is the energy that actually goes into propelling the arrow. Basically it is the energy that is left over from the stored energy after all of the bow system friction is accounted for. Using The Above Graph: The area under the graph signifies the amount of energy stored by the system from brace height to full draw (power stroke). The shape of the curve is generated by a plot of draw weight in pounds against draw length in inches and gives an indication of how the bow will feel when drawn. The more rounded the curve the more "smooth" the feel of the draw cycle, however, if the curve is "squared-off" it will likely feel more aggressive. The trade off comes in performance, as the more aggressive curve is generally indicative of more stored energy and more speed.
