At a glance
The 9X4 has a stiffer 95 flex with a T28 curve, while the PX is slightly softer at 85 flex and uses a TC4 Tall New curve. The real difference is curve selection and stiffness: the 9X4 suits pure power shooters with a traditional pattern, the PX gives you a taller blade option if that fits your shot better, and it's $10 cheaper.
