Youth Big Barrel Baseball Bats: One-Piece vs. Two-Piece
One-piece baseball bats use the same material throughout the entire design. The advantage of the one-piece design is that you get a stronger, stiffer baseball bat that is generally favored by power hitters looking for as little flex as possible. In two-piece baseball bats you'll find that the handle is a separate piece from the barrel and that the two are bonded together. The advantage to a two-piece baseball bat is that its design allows the barrel to flex at the point of contact creating a trampoline effect off the barrel. Two-piece baseball bats generally have less vibration in the handle due to the separation of the handle and barrel.
Youth Big Barrel Baseball Bats: Alloy vs. Composite vs. Hybrid
Alloy baseball bats are generally constructed with a one-piece design out of aluminum or aluminum that is mixed with other metals to make a stronger product. The advantage to this strength is that it allows alloy baseball bats can have thinner, more responsive barrel walls. Composite baseball bats, on the other hand, are made out of a mixture of carbon fiber, graphite, fiberglass, and sometimes Kevlar. Many leagues are beginning to ban composite-barreled baseball bats because, as they are used, the carbon fiber weave begins to become more responsive and much "hotter" than the current standards allow. Check your league rules before buying a composite-barreled baseball adult bat. Hybrid baseball bats feature a two-piece design in which an alloy barrel is bonded to a composite handle. This makes the handle lighter and allows the alloy barrel to be made longer than on a traditional alloy baseball bat.
Youth Big Barrel Baseball Bats: Wood Baseball Bats - 2 5/8" vs. 2 3/4"
2 3/4 inch barrels are slightly larger than 2 5/8 inch barrels. 2 3/4 inch barrels give players a larger hitting surface, however this barrel size is not allowed in some leagues. Check your league rules before purchasing a bat with a 2 3/4 inch barrel.
