I played tonight with the Babolat Aerprodrive GT with LTEC 5S at 48. This string compliments the Aeropro quite nicely as it has a muted feel that takes away the boardy feel of the APD. The mix of power and control was there. I felt much better hitting with a racket with a much higher swingweight if compared with the VCORE 100. Now I have to decide if I will trade the almost new VCORE for a second APD. This is hard to decide especially when I had good hopes with the VCORE before receiving it. If I dont trade it I suppose it will stay in the closet collecting dust.
