I’ve inherited a pail of shafts. The graphites are easily identifiable, but the steel have no shaft labels at all. I don’t have a shaft measuring device. Is there a easy way, (by sight) to tell if a shaft is stiff or regular. I recall counting the steps in a shaft, the more steps, the stiffer the shaft and vice versa. By the looks of the shaft I suspect they’re stiff, but not sure.
