You cant go just by numbers. You have to look at coverstock Type Pearl/Solid/reactive/particle and Material (Monsoon,Accutread or Typhoon) etc.
These will determine overall ball motion. I have both the recharge and the prostock and they react anything but similiar! They are 2 entirely different reactions. Talk to peopla who have them that throw it like you do and decide then.
