Spine Angle Analysis of P.G.A Tour Players at setup and Impact.
Below is a list of certian P.G.A Tour players I have analysed to see how much the spine angle changed from address to impact. The average amateur often struggles with the spine at impact raising relative to where it was at address. What you will see with the best players in the world is the opposite pattern. I have used a - to indicate a lowering in degrees and a + to indicate a raising in angle. Ian Poulter: Reduces by -6* from 50 to 44(Hybrid)
Justin Rose: -2* from 51 to
