Pro's: MOI is a measure that is more representative to how it feels to swing a club.

Con's: If you MOI match a set of irons you will get shorter long irons than normal. And the yardage difference between two clubs will shrink.

Conclusion: I think MOI matching towards a gradually increasing MOI would be a good idea.

I'm not a club fitter but that's how I see it anyway
