I'm considering buying a used AP1 712 6-iron (used) and a DG Hi-Launch Sensicore S300 shaft (new). If I were to replace the existing shaft for this used 6-iron, would I buy a 37.5" shaft or a 38"? Specs show a stock AP1 712 6-iron as 37.5 in length. Just not sure if that includes the head or is that just the shaft. A bit of advise on replacing the shaft and what length to buying would be greatly appreciated.
Thanks!
