I have a Pure Drive Roddick Cortex and an Aeropro Drive w/o Cortex. These days I have been hitting with the Aeropro Drive w/o Cortex and I noticed that in the normal direction of the racquet face the racquet is very flexible. And there is vibration fluttering back and forth through the whole racquet after each shot. I don't notice that in my Pure Drive Roddick Cortex.
Is this vibration caused by the lack of no-Cortex or by the Aeropro beam design (Aero beam is flat and the Pure Drive beam is round)?
