Just curious are you still using the 2018 Pure Drive and what string setups do you like? I am doing the exact same transition right now RF97 to 2018 Pure Drive.I have gone from the Wilson RF97 to the 2018 Babolat Pure Drive. The changes in the new PD made the transition very seamless. I use a similar string set up in the PD that I used in the RF97. There are so many good racquets on the market nowadays that it can be a little overwhelming to "find" the one that you feel is perfect for you. I feel that the good news is there are multiple options and offerings that can fit everyone's game. Obviously string set up and grip size play into the equation as well. A fun debate/discussion that we can probably never all come to a complete consensus.
Have only played one match so far and felt it went pretty well. The biggest difference I noticed is my ball did not have the same heaviness to it as with the RF97. But that is to be expected given the difference in weight and swing weight. Also the RF97 is unmatched with it's ability to pick up balls hit into your body and re-direct them with authority.
My reason for switching is for better maneuverability and I certainly notice the difference there.
I strung it up with RPM Blast 17 at 51 lbs and it felt a little stiff for me.
