Kevin Kernan explores the reasons Little League is opposed to a ban on non-wood bats.

• More than 10 years ago, the major manufacturers of non-wood bats reached an agreement with Little League to limit their bats to a "Bat Performance Factor" (BPF) of 1.15. ... The BPF is essentially a measure of a non-wood bat's performance (how fast the ball exits the bat when hit) in relation to a standard wood bat's rating of 1.00. A very good wood bat's BPF is 1.15.

• That means today's best non-wood bats (usually made of aluminum) used in Little League perform statistically the same, in terms of how fast the ball exits the bat, as the best wood bats.

• For the last 10 years, bat manufacturers have only been producing non-wood bats for play in Little League that do not exceed the 1.15 BPF. Most of these bats are already printed with the BPF of 1.15, but beginning in 2009, all bats used in Little League Baseball must be imprinted with the BPF.

The article goes on to point out that even though the bats are swung faster than aluminum, the transfer of momentum is less. I personally like wooden bats better, since that's what you use in the pros. I understand the costs, however, but according to little leagues, injuries isn't one of them. The whole post is well worth the read.
