At a glance
The 9X4 is stiffer (85 flex) with a TC2 curve, while the PX is softer (75 flex) with a TC2.5 curve and costs $30 less. If you have a strong shot and want the tightest, most responsive feel, go 9X4. If you want slightly more forgiveness and a mid-curve option at a better price, the PX makes more sense.
