I'm a 45-year-old lefthanded 3.5 singles and doubles player. My two-handed backhand is stronger than my forehand and sometimes (on returns) I'll hit around my forehand. Should I try to develop a one-handed slice? I've been trying to hit a two-handed slice but oftentimes I just get more of a backspin shot rather than a slice. Is it much more difficult to hit a two-handed slice?
