Balls!

[ukumpire]

Something a little away from the Slots! But a subject that has begun to Baffle me somewhat:
Why are there so many different kinds of softballs that state the same thing?
Most, if not all balls are Max 375lbs and then are .47 or .44 COR. Taking .44 COR out of this question.
Why then do the .47 COR's all vary in feel and playing ability.
Do not think it is right to name brands on this thread (Someone over there may sue my Arse! ), but all brands have different codes, and although they all say 'Leather' some feel more rubbery than others and the players can feel the difference 'at bat' or when pitching.
Just Curiuos

If we have someone here from the maufacturing side, I would be keen to hear from them via e-mail, otherwise general feedback will be good on this thread.
