When I tried out the 910d3 driver at my local golf shop I was only able to test it in an indoor simulator. I was getting good results from the PX 7C3 but usually go with an Xstiff. I was going to do a 7A3, but opted for a 7B3 instead. Now that I have my club I love the feel of the shaft and head, but I am launching the ball too high. I now wish I would have went with the 7A3. Do you guys offer any swapping of shafts? The only reason I would ask is they don't carry any X stiff shafts at Austads so I was never really able to fit myself really well. Also on paper, does the PX shaft launch lower than the RIP 70X? Thanks!
