Pros: My son is 11 and has been using the bat ( 30/20 ) for about a week now. The bat has good pop out of the box. He said the bat has zero vibration. Its a well balanced bat he used he Louisville Slugger 517 (29/19) last year. This is so well balanced it actually feels lighter to him.
Cons: its a great looking bat but the white paint is already chipping unfortunately.
