Why the Traditional Slice Backhand is messing you up - JeffSalzensteinTennis
He gives a good argument for variations of the slice backhand and the video is descriptive so I've included it. As a comment related to the video, here is my take on whether this is new or just used more often. I think also that the changing equipment has added to this option in style.
I learned the old-school slice backhand with a wood frame by watching Rosewall. I often used the "modern" style, as Jeff describes it for handling lower balls or choosing to add sidespin. Done to an extreme, I remember it as "peeling the orange, " and we'd use that on "body volleys" or an approach. I believe I've seen Rafa use that fairly often, while Fed used it for the same purpose among his many variations.
Here is a good demo that I found on Youtube if you want an example of a very smooth and effective looking slice backhand.
