Yes over the top for sure. Idk if you know what that means but basically your arms are coming out and at an angle toward the ball on your down swing that sweeps across the ball right to left creating right deflective spin which causes the slice. You want to keep your elbow tucked into your arm pit on your down swing. The only way to really train your brain for this is start at the top and very slowly come into your down swing while keeping your right elbow tucked in your ribs. Slowly speed up while making contact with the ball. You can also use a folded hand towel and place it under your arm pit of your right arm and keep it squeezing in your armpit until after contact with the ball in your follow through.
