no, it's simply due to the design of the shaft itself; also i'd bet that on a launch monitor the project x would launch higher but not spin as much thus your perceived lower ball flight is simply a result of using a project x shaft..higher initial launch with a flatter overall flight.
Jim - have you seen how the differences show up in trackman/flightscope club variables? Higher launch would register higher dynamic loft, but what would be the cause of the lower spin? I would have guessed lower spin loft, but then I'm struggling to visualise how a shaft change could deliver both higher dynamic loft and lower spin loft. Is this what happens, or is there another variable that impacts spin rates?
