Hello, i play with a Kason F9 strung with nanogy 95 @11kg. Yet as it has quite a flexible shaft and is more on the hold side I find it lacking a little repulsion on flat drives. Which string would you recomend me to try to avoid this problem? Bg 65ti came to mind so as nanogy 98. I would prefer a quite thin string to keep my BP not too much towards the head.Thanks for your answers
