I just discovered an interesting stat: I found that ATP pros with 1-handed backhands use racquets with an average weight of 12.8 ounces, while pros with 2-handed backhands have an average racquet weight of 12.4 oz. This is a huge difference! I used Jura's data, and converted to strung specs. Also, my data is incomplete, as I only used the players on the list who I had seen play and whom I knew for sure what type of backhand they used (30 total players, 15 in each category). If someone is willing to do the research we can get a more complete dataset. Edit: I now have the whole list included thanks to Fitzroy - see posts below. My question is... why? My first thought is that a 1hb depends more on the inertia in the racquet for stability, while a 2hb is naturally more stable, so it is easier to return a heavy incoming shot with a lighter racquet.
