So I just switched from my APD to the M-Fil 200. Right now I am loving it. I think the APD serves terribly. My serve has increased 10 fold with the M-Fil. My groundstrokes have also gain alot of control. The M-Fil feels alot heavier to swing but this isnt a bad thing. I know the racquets aren't that similar, but does anyone have experience with both, or just one. What do you guys think about them.
