All Sterling Irons™ single length irons have the exact same flex, lie angle, weight and length so you’ll only focus on one swing instead of having to learn 8 different iron swings.
As a perfect example: If you were to get a top firearms expert to tell you how to arm your home, he would say to have several units of the same gun. So, if you chose Colt 45’s then you’d only have Colt 45’s around the house.
This way when something goes bump in the night and you pick one up tired and sleepy, you know what you have in your hand and you know how to use it. To quote a saying where the author is unknown ~ Beware the man with one gun – he knows how to use it!
