I found this video that explains how adjustable driver hosels work. I know that when you loft up any brand of driver that the face will appear more closed at address. I assumed that the club would need to be turned in my hands to square the clubface and that would be the true adjusted loft. My instructor from last year said otherwise so I would like to truly understand what is happening when I add or subtract loft from my driver using an adjustable hosel. This video explains it nicely but it seems like Tom is trying to sell something and I am not sure I trust his views as facts.
Do you agree with Tom? If not please explain where you differ.
What is the difference between setting a driver in the loft up "face closed" and draw setting "face closed"
