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.

Drop is length minus weight: a 30 in, 20 oz bat is a -10. A bigger drop number means a lighter bat for its length. Younger players use -10 to -13; USSSA 13U is usually capped at -5; high school and college are -3.

Tip: Check the drop your league allows before you look at anything else.

A thinner barrel (under about 2.45 in on a wood bat), with less wood to hit with. Its size does not decide the balance: some skinny-barrel bats are end-loaded.

A handle under about 0.93 in. It whips through the zone and feels fast, but it stings more on mis-hits and, in wood, breaks more easily. Common on pro models.

Tip: Thin handles and young hands do not mix well in cold weather; expect sting.

Extra weight toward the end of the barrel, so the bat swings heavier than its number. For some players it gives a better feel for where the barrel is; whether it suits yours depends on how consistently they deliver the barrel. End load is not barrel size: some skinny-barrel bats are end-loaded.

Tip: An end-loaded bat that feels heavy is the most common sizing mistake we see.
