I agree with Chris entirely. Also, aluminum bats tend to have a wider sweet spot, so ball hit closer to the hands tend to go farther than those hits coming off wooden bats.

One effort to protect infielders and pitchers from such harder hits was to mandate for high school ball that the bats could have a "drop" between the length and weight of no more than "-3". In other words, a 33 inch aluminum bat for high school ball has to weigh at least 30 ounces.

> They come off the bat faster and thus fly farther due to the greater rigidity of aluminum. Less energy is absorbed by the bat and thus is transmitted back into the ball. That's why aluminum bats aren't allowed in the pros. Every stadium would have to be redesigned (as golf courses have had to be lengthened due to the introduction of extremely rigid titanium drivers).
