I just got a new SUMO 9.5* on ebay with a VS Proto 65 R in it. I have an Ashton X1 8.5* with a V2 7070 R at 44.75" I was curious about the Differences and similarities between the shafts. I also got another V2 7070 R that I could switch out. If I do how much could I expect to get for the pull? It would be done by a club making professional. So I would assume the tip would be good.
