Got a chance to hit with both of these today for a very short time. Initial impressions. Maxply has loads of power. Can't remember the last time I hit with a frame where I couldn't keep the ball in the court. Matter of fact, I was consistently hitting halfway up the curtain at the back of the court on groundies. The M-Fil 300 felt nice. Solid and comfortable with none of the lightweight hollow feel of the 300G. Nice frame.
