Not an expert so don't go to that section.I started a thread on that very subject a little while back in the experts section pal:

From the information garnered, I have a lot of forward shaft lean at impact moving the impact marks up the face, which was corroborated by my Mizzy DNA fitting data having a release factor of 1 (IE very late).
The characteristics my ball flight are more than acceptable so I'm not too worried at the minute.
