Chakvetadze has more pace on her shots than people give her credit for. I think slightly more than Jankovic anyway. I might be wrong, it's pretty neck and neck between those two. I think Anna's normal rally shot is slightly faster but when Jankovic is trying to open up the court or hit a winner, hers is faster.
Also as the TS mentioned, it's difficult to pick between Serena and Ana because Ana's FH is probably bigger than either of Serena's strokes, but Serena is more balanced in terms of being able to belt it off both wings.
3. Henin - NO, I'M NOT JOKING. Hard hitting isn't just about how big you are - it's about timing and technique as well.
most girls these days have big forehands, wonder which player has their backhand bigger than there forehand.
Yeah but there is a big disparity between the power of her forehand and backhand unlike Masha, Justine and the Williams sisters. To answer your question I would say that Hingis and Jankovic have bigger backhands than forehands
