Both wooden and metal alloy (generally aluminum) bats are generally permitted in amateur baseball. Metal alloy bats are generally regarded as being capable of hitting a ball faster and farther with the same power. However, increasing numbers of "wooden bat leagues" have emerged in recent years, reflecting a trend back to wood over safety concerns and, in the case of collegiate summer baseball wood-bat leagues, to better prepare players for the professional leagues that require wood bats. Metal alloy bats can send a ball towards an unprotected pitcher's head up to 60 ft 6 in (18.44 m) away at a velocity far too high for the pitcher to get out of the way in time. Some amateur baseball organizations enforce bat manufacturing and testing standards which attempt to limit maximum ball speed for wood and non-wood bats.
One of the major advantages of wood fungo has to do with the feel of your hands. While the metal ones feature a conventional metal bat knob, their wood counterparts usually come in 2 knob designs. The conventional metal-bat style knob is excellent for folks whose hands are sweaty. The flared knob is amazing for those that do not want the knob beating their hand’s bottom which is uncomfortable during practice.
