Anyone that suggests that the bat does not matter is simply not paying attention. Some say bat technology killed the slow pitch game. First came the double wall demarini. That was the first time I can recall outfielders moving back based on the bat, not the hitter. That is also about the time that rounding the bases was no longer required after hitting a homerun. Then came the original Miken Ultra, which was the sickest bat EVER! I actually quit swinging it, after I hit a lady sitting in the bleachers of another field. Then came the bat standards and lower core and compression balls. Manufacturers figured out that they could beat the bat standards by building a bat that got hotter as you used it. That is why you would see dudes beating their $300.00 bats against trees. When that was not enough for Mr. 160 lb hero to hit a bomb, he started shaving his $300.00 bat.
There is a reason one bat costs $40.00 and another $300.00. A good bat will add both feet and mph's.
