Having watched my son hit with all types of bats from metal to one piece wood to composite wood I see the following advantages for each. The metal bumps up (unrealistic?) performance, requires less skill to hit with due in part to a larger sweet spot along with reduced breakage possibilities . The one piece wood gives you only expected performance, requiring much higher skill levels due to small sweet spot and possibilities of breakage. The third option, composite wood, combines the two incorporating the smaller sweet spot with performance close to one piece wood while having reduced breakage potential. At least at the HS level the composite wood bats make sense from a player development aspect as well as an economic option.
If you want to be a better hitter swing some type of wood. It's that simple.
