I hit with the a demo today with 4g in it and really enjoyed this racquet. I think its just a solid clean feeling racquet. I didn't notice a dramatic difference in spin production between it and my 2013 APD plus, but my strokes were really clean with it, and I felt like I had excellent control over the ball. No sour points with the racquet at all. Its definitely a smoother feeling racquet compared to the APD, which has a battering ram quality about it. On serve I was exceptionally consistent. And spin, and racquet head speed is really easy to access. I hit some kick serves in practice that had my draw drop. If I could make them a repeatable affair in match play with this racquet I would switch in a heart beat. Again, the thing that impressed me the most with this racquet was how clean my overall game was with it. I would love to try different strings in this racquet and maybe a little lead at 3 and 9.
