So I am currently using a Nanoray Z-Speed 2U and was thinking about purchasing a new racket. I am an intermediate player, but I can use the 2U Z-Speed pretty easily. I'm thinking about buying a Z-Force II, but I'm not sure if I should get the 4U or the 3U. I mainly play doubles. Since I'm used to a 2U Z-Speed, will it be an easy transition going for the 3U Z-Force II? Or should I get the 4U? Thank you for the replies!
