Go 4 Yonex VCore 98D or the new Xi98 . More power than the Prestige and almost the same control. I strung mine with poly 48/46 lbs. It feel stiff but i didn't had any arm problems .
my second racquet is Babolat Pure Drive Roddick GT. The Roddick is also a nice racquet but has just a little more power than i like.
