This can be the very last part of this series. I still have to do my 3-wood, transfer out the KBS C-Taper shafts in my wedges with the KBS C-Taper R shafts and I can also be getting my YAR Putter day after today. I will shop the ones for regular blog posts. First, right here are my final specs:

Here are a number of my final thoughts on the MOI and MBI matching process:

THE MAIN BENEFITS ARE BALL FLIGHT, SPIN AND FEEL

With my irons that had been best MOI matched, I observed that the lengthy irons flew decrease and the fast irons flew better. With MBI, I changed into able to hit the ball higher and produce greater spin with the lengthy irons even as getting a greater penetrating ball flight with the quick irons. While I can't reconcile with Monte Doherty's claims that his route changed when his Balance Index were given towards his goal, I do trust him while he states that he gained distance.

From a simple perspective, if we've a greater percent of the burden in the direction of the pinnacle, that would logically produce a better release with extra spin. Thus, if you have a greater percentage of weight in the shaft grip, in an effort to produce a decrease launch and much less spin.

The hassle we've with lengthy irons is they tend to fly low and now not get much spin. Thus with MBI, we have become a better percent of weight inside the head and for that reason generating a better release and extra spin. Conversely, with the fast irons we are becoming a smaller percent of the burden inside the head and thus the ball will penetrate extra in flight. These changes in release and spin have allowed me to gain a bit extra distance (about a 1/2 club). I think it lets in for better yardage gapping as properly. And it is why I agree with Doherty changed into hitting his golf equipment similarly; the distribution of weight healthy his swing better.

With the texture, I suppose it's miles tremendous to get the texture of the heft of the golf equipment the identical. Imagine your brain seeking to adapt to the texture of a 3-iron which generally has a low MBI on one shot after which switch to a 9-iron with a high MBI on the subsequent shot. The distribution of weight is very different and I suppose it throws a lot of golfers off.

MBI EXPOSES A FLAW IN IRON FITTING

The ordinary irons fitting, regardless of MOI matching, includes hitting a 6-iron until the clubfitter can find specs and additives that produces the finest outcomes for the golfer. Then the rest of the set is constructed according to the baseline, the 6-iron.

I agree with the flaw here is that the golfer finally ends up being optimally equipped for the 6-iron.

If you ask golfers 'what's your favored membership to your bag?'

I would say that the majority of them will say the 6-iron. If now not, they may say the following closest membership, both the five-iron or the 7-iron. Again, they have been equipped for a 6-iron.

I accept as true with that if we have been to apply a 3-iron as a baseline, we would discover golfers being equipped for lighter shafts. Conversely, if the Pitching Wedge was the baseline I agree with that most golfers might be equipped for heavier shafts.

MBI EXPOSES A FLAW IN IRON SHAFT DESIGN

Iron shafts are designed the same inside the sense that the longer the club, the extra the shaft weighs. Looking at how shafts are designed in woods after which in irons, I begin to see some failed common sense within the design.

Typically we use the lightest shaft in our driving force. We then have heavier shaft weights in our three-wooden after which a heavier shaft weight within the 5-wood or the hybrid.

Yet, with irons we go the alternative manner around. With the heaviest being the 2-iron after which they will typically get incrementally lighter. So with woods we've them getting incrementally heavier after which with the irons they get incrementally lighter.

And with my findings that the distribution of weight affects the ball flight and spin, we will see why the iron shaft layout is defective. It's in all likelihood to produce trajectory that is too low with the long irons and too excessive with the short irons.

MOI MATCHING BY ITSELF STILL HAS BENEFITS

While we can't match the Balance Index just by using using MOI matching, I discovered that it allows slender the space inside the Balance Index between golf equipment. I disassembled my Wishon 555 irons that are stand-on my own MOI matched golf equipment and located that Balance Index ranged from 35-45.

When I did the identical with my swingweight matched Titleist 690 MB irons, the Balance Index ranged from 32-56.

I even have additionally visible time and time again wherein MOI matching by itself substantially improves a golfer's impact dispersion.

YOU NEED THE RIGHT TOOLS

Like some thing you put together, it's a lot less complicated if you have the right gear. I could endorse the GolfMechanix MOI Auditor Machine, the Balance Point measuring setup as defined in Doherty's spreadsheet, a great virtual scale (measuring to the nearest tenth), Wishon's Shaft Bend Profile software and lots of lead tape.
