Wrist pain - you need a racquet of lower flex. Maybe slightly heavier (depends).
I had wrist pain when I used Babolat Pure Drive (flex 72).
I changed to Babolate Pure Storm Tour (flex 66) and my wrist got a lot better.
I then changed to Wilson Pro Staff Six.One (flex 64) and my wrist is now completely pain free.
