Subsonic What shaft exactly, are you wanting to see in them, to make you buy?
I laugh when people say such things. Knowing they have not bought other brand irons that are /will be, same pricing or (most) even cheaper. And Steve has even said we could get heads only from Giga Golf, and they have a very similar iron head.....complete iron at only $62/ea. . So does PXG (similar + brand recognition), and you can even get the specs you want, with shaft choice. There are a few other companies with similar heads that have really good pricing, less than Costco will probably have.
Just sayin'......again.....a lot of hot air about a subject no one will buy. 😉
