My daughter has a nice RH swing and is 10 playing 12u. Only issue is while her swing is sound at times struggles driving the ball in games. I doubt she will ever be a "power hitter" but able to drive the ball gap to gap would prob be good as she can pick it up the middle with a good arm. Rarely strikes out usually makes contact. She's 5' 82lbs very quick feet and a fast learner but wouldn't say she's fast. From the right side with simulated swing consistently 3.3 with occasionally a 3.2. My original plan was to stay RH see how summer ends up when she turns 11 and make the switch but afraid by that time may be too late. Had a slapping lesson today and picked it up real quick. I am thinking about working on both until we can fig it out as we hit RH at home but start the slapping as a back up plan. Bad idea??? Wish I had crystal ball to say she would get faster if 3.0 from left now be a no brainier. Thanks from a stressed out dad
