Just added 1/2 inch to the MP57's, and yes, slightly better balanced now Jon to my way of thinking.
I do like something that feels a touch "head heavy", as I find it helps me to know where it is in the swing, and helps with the timing of the release.
A lot of the irons I try at work feel really light, (no doubt more evenly balanced and with lighter shafts as well), and I just don't like the feel of many of them.
Unfortunately Gaz, most of the current modern iron heads are 5 to 8 grams lighter nowadays.
OEM have been taking weight out of the heads and delofting for several years. So a 5 iron head from the 80's and 90's is 254 grams and 27 to 30 degrees with 59 to 60 lie angle.
Now the average 5 iron head weighs between 247 and 250 grams, with anywhere from 23 to 26 of loft and 61 to 63 lie angle, quite upright.
That's a little clue for those golfers wondering why it's hard to get a 2, 3 and now even 4 irons in sets.
The real con is in the fitting gear that's used to help sell most modern irons and the specs that the OEM have on their websites. The quick-fit universal adaptors used on the irons, adds about 10 to 15 grams to the head end and balances the clubs to about the D2/3 area, sometimes more.
But when you get your shiney new clubs they don't even come close to the same specs that you have tried in the retail outlet or in the specialist fitting centres.
Currently a standard length 5 iron with the typical lighter sub 100 gram steel shaft will balance at about C7 to C9.
The typical american made 5 iron will be 38.5" ( 1/2" to 3/4" longer than the average ) at around D0 with 23 to 26 degree loft and 62 + in the lie angle and have an 85 to 100 gram active cheapy steel shaft. That's what the yanks think the average male golfer needs, go figure.
Hard to get a 5 iron demo anymore, most of the demo irons in fitting carts are a 7 iron, why because their specs are getting closer to the older 5 irons from pre 2000.
I get alot of customers with brand new gear ask the question about the lack of balance.
And when it's explained properly they always ask why the OEM and retailer can't at least get it right and or stick to the website standards ???
