The Storm Pack comes with 3 Ritend Weights (20oz, 16oz & 12oz) to give you the maximum variety to increase your strength and speed at the plate! Ritend promotes hands to the ball because the weight is at the knob end of the bat. Traditional bat weights are at the far end of the bat. Although traditional weights fell like they are making your hands quicker it actually creates casting by forcing your hands away from your body due to centrifugal force. This causes the swing to get long, hence not quick and slow. Click the YouTube Video link to see the Ritend Bat Weight in action.
