^ I think she doesn't need them against Riske (either)
Daniela's problem starts from her raquest and finishing in brain.
I am telling this for many many years now.
Her raquest is worng and not suitable to her current game style. Her STRINGS are the worst possible. How "idiots" her team and specially Prince should be not to suggest something new. She needs a raquest change the soonest possible.
Wilson would be perfect for her or Babolat as she needs control. But I guess she's too lazy to do changes at this stage of her career.
