I would strongly suggest practicing getting those slices better. I had to do a drill with my coach where he gave me those balls and I had to basically come really low under them and "throw them into a corner" with topspin. Once you come in to the net, you don want to be running backwards. You want to keep moving forward and end the point.
What I like to do sometimes is hit a drop shot, and the guy attacking it is prone to slicing it back DTL, I will get ready for that and get there for it early. It sets up a pretty easy CC lob for a winner.
