Re: Transition From Radical Team to...........
if he's looking for an easy to use players racket then none of the rackets you mentioned really fit the bill; really they are all advanced players rackets. he may prefer something in between the radical team and the rackets you've listed, such as:
babolat aero storm
dunlop aerogel 300
head microgel radical mp
yonex rds 002
they are all what you would call light players rackets. they are heavier than the radical team, so they give more stability, and the extra weight and smaller headsize give more control
