yup, its basically just "tuning" for bats. Like we tune motorcycles to get the best performance people do so with bats as well When you're swinging $3-500 sticks, it blows to wear out the bat before its ever really broken in which is half the case with mine. Had it 5 years and he thinks he can do some magic so I figure for $20 why not. The other 2 are brand new ones so those will really take off
