Flexpoint or M-Fil ? Flexpoint is going to increase flex at 3 & 9 to get more control. M-Fil is increasing stiffness at 3 & 9 to get more stability and larger sweet spot. They are both well-known on producing true players' racquet, highly flexible with dense pattern, but they are in totally different direction now. What do you think ? Perhaps somebody who playtest both of them may give some hint.
