|The Hammer Amp Up brings a new level of energy to the pins. The Amp Up combines Hammerís high revving PowerShot core with a pearlized version of the Overdrive coverstock. With the original Amp, Hammer has a continuous hooking ball that was best in medium to heavy oil. Amp Up gives Hammer bowlers the sharpest backend move since the First Blood, and is best on medium to medium-dry lane conditions. Colour Purple/Gold/Green which will vary from that shown.
