Greetings – Hi Britt, do you ever test irons shorter than the 6 iron?  What have you found as a norm as clubs get shorter?  Does the MPF tend to transfer equally?  I would think that the MPF would decrease in shorter irons and increase in the longer, since a lot of the companies will push the COG higher in wedges, etc to allow a lower flight.  Maybe I’m way off base, but curious.  Titleist for instance loses the Tungsten weighting in the higher irons, which would theoretically have less MOI, etc…  Take a 9 iron for example; would one notice a large amount of forgiveness difference between MB and AP2?  Thanks!
