not really sure. i know the bbcor bats are going to make a huge difference. but, i just read an article on kyle carter from columbus, ga. he won a home run derby with 7 in the prelims and 7 more in final. he had the longest homerun at 487 feet i think. doesn't sound like bbcor bats, but i think the article stated no other contestant hit 3 homeruns. kid has a lot of power for his size. he has 45 career homeruns and he thinks he will break the ga state record career mark of 69. to do this it will take 25 this year. pretty big goal. i guess time will tell.
