Wood Bats

I have had very good experiences from swinging a lot of wood in my own practice sessions with my dad and hitting with metal in team practices and games. The wood is more top heavy, and has a much smaller sweet spot, and also doesn't hit the ball quite as hard. You must swing the wood the same way you swing the metal. That is the most important factor. If you dont, then you are messing up your swing, unless maybe swinging the wood is helping you with a flaw in your swing mechanics. And maybe if you are hitting good with the wood, and not so good with metal, you might want to swing a lot more with the wood and get the muscle memory down so you can swing your metal the same way.

Its not how good you are; its how well you play - scout

I'd say swinging wood should make you a better hitter overall. Look at all the solid hitters at the wood bat events nowadays. They have trained with wood and are better hitters for having done so. I have my boys swinging wood all winter long and they love it. When they get the aluminum in hand for spring games, they should be pounding the ball. However, both have stated they may continue to use wood in their games now that they have come to love the feel of it.....good for them, the decision is theirs. Go lumber!!

Swinging wood gives you a better swing -more compact.
