I played the HX Hot Bite yesterday. I didn't dislike anything about them. Before I jump to a higher level ball I'll play these until then. I usually like buying a sleeve or two of the higher level balls though, once in a while. The B330RX really intrigues me.
I tried a box of HX Hot Bite balls this week. They performed fine, but they wear out unbelievably fast. One or two crisp iron or wedge shots and those things are a tattered mess.
