Myth One: the Hex is longer than the Voodoo. Nope, it just hooks less. The Hex actually turns sooner (by about 3-4 feet) in box than does the Voodoo in box.
Myth Two: the Hex is stronger than the Voodoo. Nope, just smoother to the pins. The Voodoo is more angular and hooks further.
Myth Three: the Hex is for lighter oil conditions and the Voodoo mediumish. Both are for mediumish conditions. The fact is, the Voodoo is better for broken down lanes because it wants to go long and flip. The Hex is a ball that despite its partial pearlization, reads the lane earlier. It will slide more on oil than will the Voodoo, but neither is for light oil.
OK, so what does this mean? (I have owned 4 voodoos and 2 hexes.) These two balls are alternatives, use them on similar conditions to give slightly different looks. They do overlap.
