Hey Alex,
Thats brilliant to hear and we’re so glad that we have been able to help you achieve this and your continued improvements! So I can definitely answer this question well as I also use DNA Pro hard both sides and have rested the DNA platinum too. Personally I stayed with the DNA Pro as the platinum is quite a big jump up in speed and because of this of course less control. For me I found I preferred having the control and easier ability to get more spin with the pro. The platinum is great for all out attacking shots but pro is more balanced and controlled, when playing slower shots, short game or wanting to generate spin.
Now of course everyone is different and will like different rubbers but I feel for most players the pro is more than fast enough but still has great control, so I would suggest sticking with what you have as the platinum is quite a bit faster.
Regards, Tom
