OkI played 2 years with 97 sq in. Vcore tour G.
Sweetspot was notably smaller than Wilson ps 90 and my old Estusa power beam which is smaller than 90.
Spin factor in Yonex was less than in both 90 sq in frames.
Sweetspot in Tour G also was shifted towards handle. Overall not an easiest frame to play with. Not sure I want to try another Yonex after that frame.
