Tennis Backhand Slice

need tennis backhand tips?
I’ve been playing tennis for 2 years. My serve, forehand are very good. I can hit topspin my forehand. Problem is I have ALWAYS used a backhand slice. My backhand slice is very powerful compared to other members on the team because of that lol…but I want to learn how to do a topspin one handed backhand. I tried using 2 hands…uncomfortable for me. anyone with great tennis skills have any info on how to hit a good one handed backhand? tips? motion, form, position, how to practice it..anything helps. thx a bunch guys.
It’s tough to tell you but I’m going to give it a shot. Low to high is key in getting topspin. If you have a fast swing you can start by taking your racquet back at shoulder level and looping it down below the level of the hitting zone and striking or brushing the back of the ball finishing high again. Your palm although closed with a racquet in your hand should be facing you. Or you should be able to see the inside of your arm after rolling over the ball. Unlike a slice where your palm finishes down and away from you. You want to be rolling over or brushing the ball as you are hitting up. If you have a slower swing you can start with the racquet waist level or lower and hit up in the same way brushing the back of the ball. Other key elements are weight transfer, stepping into the shot and creating balance with your off arm. Hope this isn’t too confusing and you are able to start getting some topspin off the backhand.
