It's simply the cost. If the cost of using wooden bats wasn't so high (due to them breaking), then there wouldn't even really be a discussion on this. Unfortunately, due to the cost, metal will probably be around for a long time. I'd personally like to see all baseball at all levels use wood bats, but I've got no clue how to fund that. Not even the sporting goods companies would be willing to donate that many bats I don't think.
Yes doctor, I am sick.
Sick of those who are spineless.
Sick of those who feel self-entitled.
Sick of those who are hypocrites.
Yes doctor, an army is forming.
Yes doctor, there will be a war.
Yes doctor, there will be blood.....
