Do not........ do NOT.... hit 47 525s with that bat. If that is seriously all you use, you should probably just sell it now.
They are logs till about 400, then they break around 500, but they will be the farthest balls you ever hit. And agreed, DO NOT HIT 525's. Use ur other bats for the good balls, and when ya hit sb12's or something of that caliber use the voltage
