I was fit for the RIP and the fitter said it was between the 60 gram and the 70 gram. I chose the 60 because he said it would be easy to ship out since they were just starting to come out. It produces to much of a range of left or right shots and I am use to the control of a heavier shaft. Is it possible to send it in and get the RIP 70 gram since there is no up charge on the shaft?
