The X has less padding in the straps/back than the 4.
Siri even stated that in his review video. The production run was suppose to have the same as the 4 but it didn't.
Hard to see the X as improved because of less padding.
I like the Clash but with the Crave/Inspire it wasn't but so needed. Good for skips though.
I'm glad MVP/Axiom have went back to releasing drivers mainly.
The over milking of putters got old rather fast.
