Every company will have cracking problems now and then. No matter what company you favor or what company you are interested in, save for the tales of woe that local bowlers tell, you'll find some people who have had cracking problems and many that haven't.
Were there some balls in particular that had cracking issues? Sure. The Paradigm and Passion, I remember reading about the EPX-T1 as well. Happens to every company from time to time.
