At a glance
The 9X4 is $20 cheaper and flexes stiffer at 95, while the PX is slightly softer at 85 and comes with a mid-curve blade instead of a pure heel curve. Both have the same low kick and pro-spec build, so the choice comes down to whether you want maximum stiffness and saving a few bucks or prefer a bit more flex with a different blade pattern.
