I had two Armortec Tour racquets and both are gone due to racquet clash. Now I want a new one similar to Armortec Tour/Armortec 600 but with a stiffer shaft. That is, an overall light racquet like 4U weight but head heavy like Armortec, and the shaft is stiffer than Armortec Tour/Armortec 600 perhaps like the stiffness of Acsaber 8DX or Acsaber 10. Not necessarily a Yonex brand. Any brand is ok, and any price is ok. Please give me your recommendation. Thanks in advance.
