It will be easier to answer if you can kindly give some more details as to what is your game style (offensive or defensive, singles or doubles) and the price range in which you are looking raquet for.

Nevertheless, for regular use you can go for Yonex’s Nanoray 4i Light raquet. If it doesn’t suits you, search for raquets which mention 5U as the weight, those are the lightest raquets, weighing between 75–79 gms.
