Just an observation...not an accusation...
I, too, have had problems with Ebonite/Hammer stuff cracking too often. Certainly not every Ebonite/Hammer ball has done so, but enough to make me a little leary. I owned three Vortex 2, one of the greatest balls ever, and everyone of them cracked, especially around the fingers. One of them from the pin to the fingers, one of them from the thumb to the pin, and the other one cracked in the bridge and surface cracks all around the fingers. I also have had three Big Blue Pearls and have experienced cracking around the fingers as well. My son has a a Big Blue that has numerous cracks as well.
Other stuff has been perfect: pearl blade with 100+ games still going great, Sling Blade great, Sharp Blade great, etc.
I don't know if it is a quality control issue or maybe just the composition of the balls which make them more or less likely to have problems. I focus on the company simply because I have owned all companies equipment at various times and the only company I have had multiple problems with is Ebonite/Hammer.
All this is to say that I will still buy Ebonite/Hammer stuff, but not until I hear about some of the durability issues associated with some of their equipment.
