My favorite rig to see these days is one of the older wheel cam bows that center shoots about 1/8" off the riser.... someone will either have an overdraw or a plunger style rest on it, and decide its time for a whisker buscuit or something like that. Of course the WB won't slide over enough to center shoot the bow correctly, or else something will be in the way... so what is the answer.... mount the WB on the backside (target side) of the bow..... I call it the "Polish Overdraw".
