LONG BARREL PROFILE: Refers to a Fastpitch Softball Bat with the maximum legal diameter measuring the longest from the end cap to a point where the barrel begins to taper down providing larger contact surface and theoretically a larger sweet spot.

MINUS (-): The negative number on the Fastpitch Softball Bat refers to the differential between the length and weight of a bat. This is also referred sometimes as the "drop". As an example a (-10) Fastpitch Softball Bat on a 30in. (length) bat would mean the bat weighs 20oz.. Generally speaking, Fastpitch Softball Bats range from (-8) to (-13) drop.

ROTATION INDEX: This is a DeMarini innovation designed to extend a Fastpitch Softball Bat's life. A series of numbers encircle the base of the bat barrel. The first time you use a Fastpitch Softball Bat with a rotation index pay attention to the number facing you when you hit. After every hit simply rotate the bat to the next number. Utilizing this method evens out the number of hits on the barrel and will reduce flat spots which could occur over time in a Fastpitch Softball Bat.

SWEET SPOT: This is an area of the Fastpitch Softball Bat's barrel (approximately 5-7 inches from the end of the barrel) where the batted-ball speed is the highest and the sensation in the hands is minimized.

TAPER: This term refers to the handle diameter of the Fastpitch Softball Bat which must fit a player's hands comfortably providing a good grip. Most bats taper is 31/32 of an inch with some being 29/32 of an inch.

TITANIUM BATS: This is a material used in the construction of some Fastpitch Softball Bats that result in bats that are stronger and lighter than high-grade aluminum. Titanium bats generally have an aluminum core and titanium lining or wall. Some softball associations, notably both the ASA and USSSA have banned the use of these are very expensive titanium bats in their sanctioned softball leagues - so make certain you check with your association.

TRAMPOLINE EFFECT: A softball experiences a certain amount of deformation during its collision with a Fastpitch Softball Bat. During the collision, the barrel of the bat compresses and expands appearing to throw the ball away. This phenomenon is unique to hollow (metal and composite) bats.

VARIABLE WALL THICKNESS: This a manufacturing process resulting in stronger, thicker areas next to thinner areas and is purported by Fastpitch Softball Bat manufacturers to make the bat less likely to dent.

VIBRATION DAMPENING: This term is used to describe vibration reduction mechanisms which attempt to reduce the vibration that causes hand discomfort when the batter swings a Fastpitch Softball Bat and connects with the pitched ball.
