You mean you're in the svc box after hitting the floating slice? I'd just get away from slicing for a while and work on a deep, floating topspin approach. It sounds crazy, you don't want to float it too high, but something that can't be attacked easily because of its depth.
If you want to knife a slice approach, you have to lean in a bit more than on a reg. slice and carve through the ball so much that you'd think it would go into the net, but the backspin lifts it over. I'm exaggerating, but that's what it has to feel like, in my exp.
