The custom shaft brochure for the 910 drivers showed the Matrix OZIK XCON6 with lower launch and lower spin than the RIP A 60(which I currentlyh game after the fitter put me there last year). The XCON6 is listed in the 2013 brochure as an option but I can't find it on the Spin/Launch chart. Where should it be on the 2013 chart? I have seen soe description of the shaft as high launch and low spin which calls into question it's position on the 2011 chart.
