Generally speaking I think it‘s a good idea to play something a little bit softer in wedges. Whether you want to go a little bit lighter or a little bit heavier is a matter of personal preference.
I grew up playing X100 in my irons. In those days Cleveland were THE wedges and their wedge flex was a S400. So I pretty much played the most common „better player“ setup (slightly softer, slightly heavier wedge). When custom became more common, I changed to X100 throughout. Similarly, when I moved to PX 6.5 and then Tour-V 125, I played them in all irons and wedges.
These days I use Modus
