Closed fader movements; Boomerang/Autobahn. Open fader movements: 3Click flare. Of course, the Swing flare is a must. Your record hand is the most important stakeholder in timing.

Your record hand has four directions: up, down, forward and back.

Try making combos with the scratches you already know by lifting your
hand on and off the record.

Won't it be better for you to execute certain scratches with a backward
movement instead the regular forward push?
