Recently a golfer over on the Wishon Golf discussion board (www.Wishongolf.Com) asked approximately unmarried period irons. This is in which each iron in the bag, regardless if it?S the three-iron or 7-iron or Pitching Wedge, might be the equal period.
In 1989, Tommy Armour Company came out with this idea in their EQL (equal length) version of irons.
Each of the irons, three through Pitching Wedge, was constructed to 37 inches long. That is about the duration of a contemporary 7-iron. Back in ?89, that became probably the length of a membership somewhere among a 6 and 7-iron. The idea behind the irons became to get the golfer to make the ?Same swing? With each membership. It was taken into consideration too radical and had too many flaws concerned with the idea for it to work. Here?S what Keith Chatham, from Precision Fit Golf in Texas had to mention:
Assuming shaft weright and grip weight are the equal:
Problems:
All head weights want to be same weight otherwise swing weights/total weight/moi might be off......Long irons may be very mild swing weight and short irons could be very heavy swingweight.
All lie angles need to be the same for every head also in any other case accuracy could be sacrificed.
Distances might be off with modern-day lofts also. Assuming all golf equipment are 7i duration, then the 5i at 7i period is probably shorter than your present day 5i, and PW at 7i duration is probably longer than your modern period PW. So lofts likely will want to be adjusted.
Bounces on sole might be the equal for all clubs except maybe three/4 ranges extra for SW. So whilst adjusting/bending golf equipment for loft, you need to ensure you don't have a scoop sole on lengthy irons or way an excessive amount of bounce in your shorter irons.
Benefits:
Only gain I see is you might hit the shorter long irons extra on-middle, but the problems above will still exist.
I typically believe Keith?S points. I might assume the advantage is that it would be extra less difficult to MOI fit the golf equipment in the event that they were the identical period. What might concern me is that so that you can do that, the pinnacle weights could ought to be the equal. And companies do no longer make iron heads the equal weight. Here?S a hyperlink to KZG Golf?S set of irons with their iron head weights.

You will see the same with other component companies like Wishon and GolfSmith. I do believe golfers and clubmakers should not only understand MOI matching, but also understand how much each of their components of the club weigh (grip, shaft, head).
And to top it off, if you can understand the shaft’s weight distribution…does it weigh more towards the butt end or towards the tip end?…the golfer and clubmaker can find a better fit.
With the single length concept, I would question if the grind, bounce and general design of the heads would ‘naturally’ cause for the higher lofted clubs, which also have more bounce, to be heavier. Edel Golf’s wedges feature extremely high bounce angle options with the CoG of the club moved away from the heel.
In order to design the wedge heads with more bounce and moving the CoG away from the heel, I was told that they had to make the heads heavier.
I have typically found that Sand Wedges at 54-56 degrees of loft typically weight around 302 grams. I measured my Edel 56° wedge at 307 grams. And yes, 5 grams of difference can make a LARGE difference in how the club feels when you are swinging it.
Anyway, my point is that I have some concern that the higher the loft of the iron which should require more bounce, that irons should inherently have a progressive weight to them and that the irons should inherently have different shaft lengths to ‘offset’ the difference in head weight. Then I would question other things, mainly yardage gapping and if a single length set of irons would need to alter their loft increments in order to get the proper yardage gapping.
A special thanks to Keith Chatham (www.precisionfitgolf.com) for help with this post.
