Dave, Your advice has been awesome in assisting w/my 6-yr old's girls development, most notably switching to placing her non-dominant hand on top for her FH. It took awhile to transition (2-3 weeks) but now, months later, it's a really reliable stroke. Also, as predicted, when she attempts a one handed FH, it looks very orthodox and, quite honestly, it looks as if she could make the switch now (though I don't want her to--I'd prefer she play a la Seles...2H primary, 1H when stretched...but we'll see). Anyhow, there has been one negative side effect. Back when she used to switch hands b/w FH and BH (a la JM Gambill) she naturally had to reset the racquet face and as such she was hitting with a nice orientation (not too open or too closed on either side). But after I switched her to your technique I got deployed for 4 months (military) and I couldn't oversee the transition so well; the side effect from attending hitting clinics has been that she now hits her BH with a bit of an open face (basically keeping the grip the same from FH to BH). She's pretty consistent like this but as you know this leads to a high to low motion imparting slice. Any tips on how to undue this so that we can get to her lback to her low to high topspin swing? Thanks.
