At a glance
The 9X4 has a stiffer 95 flex and uses True's classic T28 curve, while the PX comes in at 85 flex with the TC90TT curve. Both deliver that low-kick release feel, but the 9X4 is built for guys with real strength, and the PX gives you a slightly softer, more workable flex in a different blade pattern.
