Thanks for all suggestion.
Prokennex is a good choice. I heard a lot of good words about kinect system. I will try ki 5.
Donnay is very difficult to be tried because there is no local distribution in my country. Or import or forget it. I checked the specs and Formula 100 is very close to Pure Drive and by TW review it looks like more confortable.
And Volkls? Any suggestion?
I was checking Yonex also and Vcore 100S or 98D are good choices.
