NDHSAA has decided to use wood bats for high school baseball starting in 2007. Very good rule I think. The only thing that will suffer is the budget. It may cost more to constantly be buying new wood bats. Though at this level not as many bats will be breaking.
I think that in 5-6 years every level will use wood bats. As I watched CWS last weekend I got to thinking that all it would take would be for one of these comebackers to hit a pitcher while on ESPN. Two kids from Montana have been killed by comebackers and they finally went to all wood (legion).
I also wonder if with the technology we now have that they won't make aluminum bats with "anti-pop" What I mean by that is bats that have the same pop as wood bats, but aren't going to break. This would solve the problem of cost at the lower levels and also take care of the problem of aluminums.
