The MZE gives me more options when it comes to fletching and arrow length. It provides total clearance so I can shoot 5" feathers and not have any problems as well as shoot some of the softer vanes. These would include the new NAP vanes I want to try out. I saw the APA rest at the show and it did apear to do well. I shot one installed on a Bow Tech Liberty and it seemed like a sound rest. It is funny though that the WB is made for hunters, but in order to get the max out of it you really need to know how to tune a bow properly. The "false tune" is one aspect of that. I like the WB, but I know and understand it's limitations and it's strengths. It took about a year to fully "get the picture" though.
