Louisville Slugger maple wood composite bat, turning model RA13, in 31 to 34 inch lengths at drop -3. The page states a slightly end-loaded swing weight.

Model codeRA13
WoodComposite wood or maple
What this means

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−3
What this means

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.
