I bought an APDC last week and strung it with Prince Topsin 16 @ 62lb. Played with it and immediately felt at home with it. Spin is good and very maneuverable compare to my old Prince Graphite Oversize, and a lot easier on my wrist. My coach then lends me his O3 Hybrid Tour (strung with some type of hybrid poly - Gamma Poly and synthetic gut @ 58lb). Hitting the O3 with similar power and long loopy strokes, I found that the spin that i am able to generate from this racket is less than that of the APDC but I can feel the "pop" on every stroke even though the stingbed feels slightly stiffer, and the ball has much more power and penetration. I am looking for this type of "pop" with the APDC. Is this achievable with Poly strings (without sacrificing spin)? Or is it the racket? Can someone recommend me a topspin friendly poly string? Luxilon? Is there a general rule for tension for poly strings? Many thanks.
