Unless True Temper has recently added to its product line, there is no Dynamic Golf XP shaft. Rather, TT makes a Dynalite Gold XP shaft.

I mention this because the Dynalite line has always been a high-launch shaft, whereas the Dynamic Golf delivers a low-launch shaft. If you have been doing well with test-hitting the Dynalite, it may be you need a little extra lift on launch. Caution: shaft bend point gives a minor adjustment to ball flight. Flex and weight are more important.

I play PX 5.0 Rifle Flighted (from about 2010) in my X20 Tour irons. The flighted-shaft design intends to control launch extremes. In flighted shafts, the long irons get a little extra lift on launch, whereas the short irons get a lower launch to prevent the ball from ballooning (going too high, esp. in wind). I played early-model Dynalites on my last set of irons, and had short-iron problems on windy days.

Flighted shaft marketing is new, but the idea behind it is not. In the mid-1900s, custom clubfitters would achieve the same thing by softstepping the long-iron shafts, and hard-stepping the short-iron shafts.

The weight difference between the Dynalite Gold XP S300 and the PX 5.5 would be negligible (probably 5 grams or less). The Dynalite* "stiff" (5.8 FCM) would be about the same stiffness as your PX 5.5 shaft (6.0 FCM).

* This assumes Dynalite and Dynamic have same FCMs.

As for shaft length, get the X22 Tour irons spec sheet (should be able to find it on Callaway Pre-Owned website).

Unless you really love the X22 Tours, you might consider replacing. Several comparisons suggest X22 Tour are the most difficult to hit of Callaway's old X-family irons.
