Just thought I'd put it out there to see what anyone can come with. Was watching THIS match and at about 27 mins, Gill Clark raises an interesting point. Why does it appear to be the left handers who have the bigger smash, She raises examples of Fu, Tan and Rytter-Juhl. Personally I agree with her observation but can see no natural reason (ie non training specific) that can lead to this. I myself am I left hander and find that compared to friends of my age, ability and experience I do have the hardest hit.
