This is the Proline C271 Pure Rock Adult Maple professional wood bat. Proline uses professional grade, hand-picked Pure Rock Maple to make this bat. The unique grain structure of this wood prevents the barrel from flaking. The Pure Rock Maple is also kiln dried for optimum moisture content. The pro cupped end is ideal for controlling the weight for maximum bat speed and durability. The medium barrel offers one of the best sweet spots possible without compromising durability. Pure Rock Maple Wood bats are a stronger wood than the standard Northern White Ash models. The strength of the pure rock maple bats make them ideal for high school, college, adult, minor leagues, and major leagues. The number of major leaguers using Maple Wood bats has increased each year as their performance and durability have been unmatched. Proline: Performance Products for Championship Performances.

When using a Proline Pure Rock Maple Bat...
Make sure you hit with the Proline Lable up or down so you are using the strongest part of the bat. That's because Proline place the lable on the flat of the grain, the weak side of the wood. With the lable up or down, you'll make contact with the ball on the strongest part of the grain.
