I have an honest question about this product. Since it will not fix bad swings that cause the slice or hook (nor should it be expected), but can help with shaft deformation that can cause issues, why are those playing at the highest level not using this product. I would think that with their face angle being near perfect (comparably to us amateurs) and their swing speed being what it is, that this would be a product that would be absolutely perfect for almost every single tour player. Why is it not being used?
I think there are 2 reasons why it is not played yet. 1 is that it is very new, and according to the Harrison owner they had to pretty much cancel all tour representation the past couple of years to stay in business due to the economy. Because of this, it has not yet gotten into many professionals hands. Second, and more important, I think there are still issues with its completely staying put (not getting loose or moving) during the course of a round. I am pretty sure that professionals would not want to risk penalty or have it in the back of their mind that their club could either become illegal or not perform to specs at any given moment.
