I thought that the slice was meant to be more forgiving of contact point than topspin 1hbh? That's not my experience though, I find it much easier to topspin backhand high balls than slice them. However, I want to add the slice off the high ball to my arsenal for the sake of variety and saving energy in rallies (slice takes less energy to hit). My wrist feels in a really uncomfortable position when slicing high balls. Aren't you meant to use a continental grip? It's uncomfortable to hold the wrist in a position that allows the racket face to be closed enough to make the ball not sail long (this is what happens to most of my high backhand slices). Do you use a different slice grip when you know you're going to be hitting a high ball? If so, what? How do you get the racket head in the correct position? And should it be more closed than when hitting a slice off a normal height ball?
