Hi! I am using Polyfibre TCS with the new APD. Feels quite good but only played once with this setup at 52 string tension. Feels better in terms of feel if compared with RPM Blast 18 at 48 tension. Good access to spin and blends well with the APD. Also, getting used to the extra power and lower swingweight of this new APD. So, do you have any preferred string setup? Last time I asked you were beginning to use the racket and had not yet concentrated on finding an ideal string setup.
