I owned a JPX 8.3 for a couple years and loved it. It broke recently during a doubles clash so I bought a JPX 8.5. The 8.3 was slightly low on power for me but perfect for control. I can generate too much power with the 8.5 but slightly less control than I would love. I am playing NBG99 at 25lb, which is higher than my recommended tension. I'm confused between the JPX CX-Edition, the JPX Z8-CX and the Prototype X-2. I mostly play doubles but would like to use the same racquet for both doubles and singles. I like to play mainly for control and placement but do love to smash on and off too. I have a Fortius Tour F 4u as well but it is not at all good for control and presently I can even generate more power with the 8.5 3u than with the Fortius. Kindly suggest.
As long as you go to a reputable stringer who knows what they're doing, there are no problems going past recommended tensions.
Thanks, strung my Fortius Tour F at 26lb and it's much closer to the power and control I expect Selling off the JPX 8.5
