Golf Irons Should I Get Golf Irons That Are Stiff Or Flex?

Should I get golf irons that are stiff or flex? - golf irons

I think that would buy a new golf club iron and put a number I buy, but they have two different versions of them, and I'm sure that will get what you. I can deal with stiffness or FLEX now what do I get? I am also convinced that using a rigid or FLEX, so please tell me where to get me.
