Is there a difference between the Kuro Kage Reg graphite shafts in the 714 AP1 irons and those in the 716 AP1s?
They are the same weight (and R Flex) according to the printing on the shaft.
On the 714 shafts, "Low Balance Iron" is printed on the side. On the 716s, it says "Low Balance Constant Mass"
Would there be a difference in height and/or spin between those two shafts?
