I am 6’4” tall and require a 1” longer shaft on all of my irons. If I install a new shaft that is 1” longer does it affect the flex? Would it make a stiff flex react more like a regular or strong regular flex shaft?

If you do nothing to the head weight, the actual flex stays the same. The frequency number changes, but that just moves the dot on the graph to another point on the same flex line. As Rlafoone stated, if you reduce the head weight after adding the length in an attempt to lower the swing weight, the shaft will play stiffer. That being said, lengthening the shaft 1″ and doing nothing to the head weight may not change the actual flex, but the club will feel different than it did at the shorter length. Obviously it should feel heavier. How the flex feels is totally random. I have had some say they feel more flexible and others say they feel stiffer. The important thing is to get the length fit correct and then evaluate the performance from a ball striking and ball flight standpoint to see if it is what you want.

couple of factors here IMHO…
increasing the length will decrease the cpm (freq/flex) of the club and increase the Swingweight. To get the Swingweight back to wear it needs to be, you need to reduce the headweight (or increase the weight in grip area). This in turn brings the cpm (freq/flex) back up.
Also, if you take the club as is with the 1″ length increase and profile/measure the frequency of the club starting at 11″ from the centerline of head and thereafter every 5″ to a total of 36″ the frequency will be the same regardless of that 1″ increase.
