Pro Series Custom Mr. Nasty

Ash. Light and flexible with visible grain; flakes over time. Less common now.

Birch. Softer than maple and more forgiving of mis-hits; hardens with use. A good choice for a first wood bat and for younger players.

Maple. Dense and hard, the most common pro wood. Hits hard and holds up when the player squares the ball up; breaks rather than flakes when mis-hit. Quality varies a lot by maker.

Tip: Maple from a good maker is the best wood bat money can buy; maple from a cheap one is the worst.

A big barrel (about 2.56 in and up) gives the most hitting surface. Its size does not decide the balance: some big-barrel bats are balanced.

About 0.93 to 0.96 in. The usual choice: enough whip, enough strength.

Tip: Most players never need to think about this one.

A cone-shaped transition from handle to knob, somewhere between standard and flared.

Weight is spread evenly, so the bat feels lighter than its number. A player who uses the knob or handle to deliver the barrel often needs the weight balanced or down toward the hands. Balance is not barrel size: some big-barrel bats are balanced.

Tip: Which one is right depends on your player and how consistently they deliver the barrel.
