1. Is my grip the right size? I've added an overgrip, but my fingers still overlap quite a bit. 2. That's the grip I use for my flat serve...it's more of an eastern forehand than continental, but it's the way my hand ended up while practicing flat serves for the first time, and it feels comfortable (and is performing better than my old serve, even if heavy slice was fun for a while). I've only been serving like this for a week, so I could easily suck it up change it, but is it really "wrong"?
