awchiu Posted June 6, 2007 Report Share Posted June 6, 2007 I took a photo of a Mizuno poster at a Hong Kong golf shop with MOI data of several MP irons. It lists the Heel-to-Toe (T/H) MOI and the (U/D) Up-Down MOI for the 5 iron. It's interesting to note that the (U/D) MOI of the MP-60 is slightly HIGHER than the MP-27 (550 vs 500) From almost everyone's experience, the MP-27 is supposedly more forgiving than the MP-60, especially in the longer irons. This data is quite surprising to me. Even the MP-32 has a higher (U/D) MOI than the MP-27. I guess it's from the design of the cut muscle. The second chart compares the MOI for MP-60 and MP-30. I think this type of MOI data is quite useful in judging the comparative forgiveness and playability of the different irons. I noticed the MOI for the Fourteen TC-770 (5 iron) is 2341. This is higher than any of the MP irons. Does that mean it's more forgiving? http://www.tourspecgolf.com/catalog/product-info-1134.html (Fourteen TC-770) -Andrew Quote Link to comment Share on other sites More sharing options...

Duffer19 Posted July 1, 2007 Report Share Posted July 1, 2007 Can anyone really feel the small incremental increase or decrease in MOI? What is the name of this golf shop in HK since I am in town at the moment. Quote Link to comment Share on other sites More sharing options...
gocchin Posted July 1, 2007 Report Share Posted July 1, 2007 More MOI would typically mean more forgiveness but with iron MOI's being so small in the first place the single digit percentage increases would be noticed only minimally unlike drivers these days where some have increased over 1000+ MOI or 25% even over older generation models. That said however, manufacturers are finding ways of increasing MOI through different head designs in irons so more and more are beginning to advertise these numbers now that MOI is all the rage. Even Golf Gear, one of Japan's premier equipment magazines have started writing a lot lately on MOI increases for drivers and irons. Quote Link to comment Share on other sites More sharing options...
ramizuno13 Posted July 1, 2007 Report Share Posted July 1, 2007 When you ain't got nothing left to sell, you start looking for new avenues of advertising! What's next? Switchblade Tees!!! BTW! I don't mean Miz doesn't have anything else to sell...I like what I do for a living! Quote Link to comment Share on other sites More sharing options...
