Hello. I just purchased another Fourteen Driving iron. THis model is the one with the black cavity. According to the seller, this one doesn't have a model number. It comes with an S400, which is way too stiff for me. Is anyone familiar with this model, and know the hosel size? Here's a picture of it. Thanks

Since you won't be using the S400, you will know as soon as you pull it.

Well, I ask because I have a Dynamic gold SL regular flex shaft 4 iron pull waiting in the wings, but it's taper tip. Don't want to have the shaft pulled to find out that I cant use the pull I have.
